A 20-Gb/s transmitter is implemented in 0.13-/spl mu/m CMOS technology. An on-die 10-GHz LC oscillator phase-locked loop (PLL) creates two sinusoidal 10-GHz complementary clock phases as well as eight 2.5-GHz interleaved feedback divider clock phases. After a 2/sup 20/-1 pseudorandom bit sequence generator (PRBS) creates eight 2.5-Gb/s data streams, the eight 2.5-GHz interleaved clocks 4:1 multiplex the eight 2.5-Gb/s data streams to two 10-Gb/s data streams. 10-GHz analog sample-and-hold circuits retime the two 10-Gb/s data streams to be in phase with the 10-GHz complementary clocks. Two-tap equalization of the 10-Gb/s data streams compensate for bandwidth rolloff of the 10-Gb/s data outputs at the 10-GHz analog latches. A final 20-Gb/s 2:1 output multiplexer, clocked by the complementary 10-GHz clock phases, creates 20-Gb/s data from the two retimed 10-Gb/s data streams. The LC-VCO is integrated with the output multiplexer and analog latches, resonating the load and eliminating the need for clock buffers, reducing power supply induced jitter and static phase mismatch. Power, active die area, and jitter (rms/pk-pk) are 165 mW, 650 /spl mu/m/spl times/350 /spl mu/m, and 2.37 ps/15 ps, respectively. 相似文献

Over the last decade, SiGe HBT BiCIMOS technology has matured from a laboratory research effort to become a 50/65-GHz fT/fmax silicon-based 0.5-μm BiCMOS production technology. This progress has extended silicon-based production technology into the multigigahertz (multi-GHz) and multigigabits-per-second (multi-Gb/s) range, thus, opening up an array of wireless and wired circuit and network applications and markets. SiGe circuits are now being designed in the same application space as GaAs MESFET and HBTs, and offer the yield cost, stability and manufacturing advantages associated with conventional silicon fabrication. A wide range of microwave circuits have been built in this technology including 5.8-GHz low-noise amplifiers with 1-V supply, up to 17-GHz fully monolithic VCOs with excellent figures of merit, high-efficiency 2.4-GHz power devices with supply voltage of 1.5 V, and move complicated functions such as 2.5/5.0-GHz frequency synthesizer circuits as well as 10/12.5-Gb/s clock and data recovery PLLs. This paper focuses on several key circuit applications of SiGe BiCMOS technology and describes the performance improvements that can be obtained by its utilization in mixed-signal microwave circuit design. By way of examples, the article highlights the fact that the combination of high-bandwidth, high-gain and low-noise SiGe HBTs with dense CMOS functionality in a SiGe BiCMOS technology enables implementation of powerful single-chip transceiver architectures for multi-GHz and multi-Gb/s communication applications 相似文献

SiGe HBT and BiCMOS technologies for optical transmission and wireless communication systems 总被引:6,自引:0,他引:6
Technologies for a self-aligned SiGe heterojunction bipolar transistor (HBT) and SiGe HBTs with CMOS transistors (SiGe BiCMOS) have been developed for use in optical transmission and wireless communication systems. n-Si cap/SiGe-base multilayer fabricated by selective epitaxial growth (SEG) was used to obtain both high-speed and low-power performance for the SiGe HBTs. The process except the SEG is almost completely compatible with well-established Si bipolar-CMOS technology, and the SiGe HBT and BiCMOS were fabricated on a 200-mm wafer line. High-quality passive elements, i.e., high-precision poly-Si resistors, a high-Q varactor, an MIM capacitor, and high-Q spiral inductors have also been developed to meet the demand for integration of the sophisticated functions. A cutoff frequency of 130 GHz, a maximum oscillation frequency of 180 GHz, and an ECL gate-delay time of 5.3 ps have been demonstrated for the SiGe HBTs. An IC chipset for 40-Gb/s optical-fiber links, a single-chip 10-Gb/s transceiver large-scale IC (LSI), a 5.8-GHz electronic toll collection transceiver IC, and other practical circuits have been implemented by applying the SiGe HBT or BiCMOS technique. 相似文献

This paper presents a single-chip SONET OC-192 transceiver (transmitter and receiver) fabricated in a 90-nm mixed-signal CMOS process. The transmitter consists of a 10-GHz clock multiplier unit (CMU), 16:1 multiplexer, and 10-Gb/s output buffer. The receiver consists of a 10-Gb/s limiting input amplifier, clock and data recovery circuit (CDR), 1:16 demultiplexer, and drivers for low-voltage differential signal (LVDS) outputs. Both transmit and receive phase-locked loops employ a 10-GHz on-chip LC voltage-controlled oscillator (VCO). This transceiver exceeds all SONET OC-192 specifications with ample margin. Jitter generation at 10.66-Gb/s data rate is 18 mUI/sub pp/ (unit interval, peak-to-peak) and jitter tolerance is 0.6 UI/sub pp/ at 4-MHz jitter frequency. This transceiver requires 1.2V for the core logic and 1.8 V for input/output LVDS buffers. Multiple power supply domains are implemented here to mitigate crosstalk between receiver and transmitter. The overall power dissipation of this chip is 1.65 W. 相似文献

This paper presents the first fully integrated SONET OC-192 transmitter and receiver fabricated in a standard 0.18-/spl mu/m CMOS process. The transmitter consists of an input data register, 16-b-wide first-in-first-out (FIFO) circuit, clock multiplier unit (CMU), and 16:1 multiplexer to give a 10-Gb/s serial output. The receiver integrates an input amplifier for 10-Gb/s data, clock and data recovery circuit (CDR), 1:16 demultiplexer, and drivers for low-voltage differential signal (LVDS) outputs. An on-chip LC-type voltage-controlled oscillator (VCO) is employed by both the transmitter and receiver. The chipset operates at multiple data rates (9.95-10.71 Gb/s) with functionality compatible with the multisource agreement (MSA) for 10-Gb transponders. Both chips demonstrate SONET-compliant jitter characteristics. The transmitter 10.66-GHz output clock jitter is 0.065 UI/sub pp/ (unit interval, peak-to-peak) over a 50-kHz-80-MHz bandwidth. The receiver jitter tolerance is more than 0.4 UI/sub pp/ at high frequencies (4-80 MHz). A high level of integration and low-power consumption is achieved by using a standard CMOS process. The transmitter and receiver dissipate a total power of 1.32 W at 1.8 V and are packaged in a plastic ball grid array with a footprint of 11/spl times/11 mm/sup 2/. 相似文献

The 3.5-Gb/s, 4-ch transmitter and receiver LSI's described here include a 5-to-1 multiplexer, a 1-to-5 demultiplexer, and analog PLL circuits that can generate high-speed clock (3.5 GHz) and retimed data. The chips make it possible to connect twenty pairs of 700-Mb/s electrical ports (14-Gb/s throughput) without any external elements even for the PLL. Both the transmitter and receiver LSI are 4.5-mm-square and are fabricated by a 40-GHz 0.5-μm Si bipolar process. The transmitter LSI dissipates 2.5 W, and the receiver LSI dissipates 3.6 W. Both have -4.5- and -2-V supply voltages 相似文献

A 10-Gb/s 16:1 multiplexer, 10-GHz clock generator phase-locked loop (PLL), and 6 × 16 b input data buffer are integrated in a 0.25-μm SiGe BiCMOS technology. The chip multiplexes 16 parallel input data streams each at 622 Mb/s into a 9.953-Gb/s serial output stream. The device also produces a 9.953-GHz output clock from a 622- or 155-MHz reference frequency. The on-board 10-GHz voltage-controlled oscillator (VCO) has a 10% tuning range allowing the chip to accommodate both the SONET/SDH data rate of 9.953 Gb/s and a forward error correction coding rate of 10.664 Gb/s. The 6 × 16 b input data buffer accommodates ±2.4 ns of parallel input data phase drift at 622 Mb/s. A delay-locked loop (DLL) in the input data buffer allows the support of multiple input clocking modes. Using a clock generator PLL bandwidth of 6 MHz, the 9.953-GHz output clock exhibits a generated jitter of less than 0.05 UIP-P over a 50-kHz to 80-MHz bandwidth and jitter peaking of less than 0.05 dB 相似文献

The nonoverlapping super self-aligned structure (NOVA) is reported. Because of its nonoverlapping nature, this structure can be applied equally well to bipolar, CMOS, or BiCMOS processes. This structure effectively minimizes parasitic capacitance and resistance for both the MOS and bipolar devices. CMOS and bipolar devices are integrated into a high-performance BiCMOS technology. CMOS and emitter-coupled logic (ECL) ring oscillators with 1.5-μm lithography are reported to have delays of 128 and 87 ps/stage, respectively 相似文献

Here, we present a low-power fully integrated 10-Gb/s transceiver in 0.13-/spl mu/m CMOS. This transceiver comprises full transmit and receive functions, including 1:16 multiplex and demultiplex functions, high-sensitivity limiting amplifier, on-chip 10-GHz clock synthesizer, clock-data recovery, 10-GHz data and clock drivers, and an SFI-4 compliant 16-bit LVDS interface. The transceiver exceeds all SONET/SDH (OC-192/STM-64) jitter requirements with significant margin: receiver high-frequency jitter tolerance exceeds 0.3 UI/sub pp/ and transmitter jitter generation is 30 mUI/sub pp/. All functionality and specifications (core and I/O) are achieved with power dissipation of less than 1 W. 相似文献

This paper provides evidence that, as a result of constant-field scaling, the peak$f_T$ (approx. 0.3$hbox mA/muhbox m$ ), peak$f_ MAX$ (approx. 0.2$hbox mA/muhbox m$ ), and optimum noise figure$ NF_ MIN$ (approx. 0.15$hbox mA/muhbox m$ ) current densities of Si and SOI n-channel MOSFETs are largely unchanged over technology nodes and foundries. It is demonstrated that the characteristic current densities also remain invariant for the most common circuit topologies such as MOSFET cascodes, MOS-SiGe HBT cascodes, current-mode logic (CML) gates, and nMOS transimpedance amplifiers (TIAs) with active pMOSFET loads. As a consequence, it is proposed that constant current-density biasing schemes be applied to MOSFET analog/mixed-signal/RF and high-speed digital circuit design. This will alleviate the problem of ever-diminishing effective gate voltages as CMOS is scaled below 90 nm, and will reduce the impact of statistical process variation, temperature and bias current variation on circuit performance. The second half of the paper illustrates that constant current-density biasing allows for the porting of SiGe BiCMOS cascode operational amplifiers, low-noise CMOS TIAs, and MOS-CML and BiCMOS-CML logic gates and output drivers between technology nodes and foundries, and even from bulk CMOS to SOI processes, with little or no redesign. Examples are provided of several record-setting circuits such as: 1) SiGe BiCMOS operational amplifiers with up to 37-GHz unity gain bandwidth; 2) a 2.5-V SiGe BiCMOS high-speed logic chip set consisting of 49-GHz retimer, 40-GHz TIAs, 80-GHz output driver with pre-emphasis and output swing control; and 3) 1-V 90-nm bulk and SOI CMOS TIAs with over 26-GHz bandwidth, less than 8-dB noise figure and operating at data rates up to 38.8 Gb/s. Such building blocks are required for the next generation of low-power 40–80 Gb/s wireline transceivers. 相似文献

A 43-Gb/s receiver (Rx) and transmitter (Tx) chip set for SONET OC-768 transmission systems is reported. Both ICs are implemented in a 0.18-/spl mu/m SiGe BiCMOS technology featuring 120-GHz f/sub T/ and 100 GHz f/sub max/. The Rx includes a limiting amplifier, a half-rate clock and data recovery unit, a 1:4 demultiplexer, a frequency acquisition aid, and a frequency lock detector. Input sensitivity for a bit-error rate less than 10/sup -9/ is 40 mV and jitter generation better than 230 fs rms. The IC dissipates 2.4 W from a -3.6-V supply voltage. The Tx integrates a half-rate clock multiplier unit with a 4:1 multiplexer. Measured clock jitter generation is better than 170 fs rms. The IC consumes 2.3 W from a -3.6-V supply voltage. 相似文献

Product designs for 40-Gb/s applications fabricated from SiGe BiCMOS technologies are now becoming available. In this paper we first briefly discuss heterojunction bipolar transistor (HBT) device operation at high speed, demonstrating that perceived concerns regarding lower BV/sub CEO/ and higher current densities required to operate silicon HBTs at such high speeds do not in actuality limit design or performance. The high-speed portions of the 40-Gb/s system are then addressed individually. We demonstrate the digital capability through a 4: 1 multiplexer and a 1 : 4 demultiplexer running over 50 Gb/s error free at a -3.3-V power supply. We also demonstrate a range of analog elements, including a lumped limiting amplifier which operates with a 35-GHz bandwidth, a transimpedance amplifier with 220-/spl Omega/ gain and 49.1-GHz bandwidth, a 21.5-GHz voltage-controlled oscillator with over -100-dBc/Hz phase noise at 1-MHz offset, and a modulator driver which runs a voltage swing twice the BV/sub CEO/ of the high-speed SiGe HBT. These parts demonstrate substantial results toward product offerings, on each of the critical high-speed elements of the 40-Gb/s system. 相似文献

A divide-by-16.5 frequency divider, providing read- and write-clocks for an elastic buffer or a gearbox between 10.3125-Gb/s and quad 3.125-Gb/s transceivers in 10-G Ethernet application, is presented. The high-speed and noninteger division is designed by cascading high-speed divide-by-3 followed by divide-by-5.5 which uses double-edge-triggered flip-flops. The divide-by-3 circuit receives and generates 5.15625-GHz and 1.71875-GHz differential clocks with a 50% duty cycle, respectively. Based on current-mode logics (CMLs), the proposed divide-by-16.5 scheme is implemented in a 0.13-/spl mu/m CMOS technology to achieve over 5-GHz operation while consuming 18 mW from a 1.2-V supply. 相似文献

A multichannel transmitter (TX) and receiver (RX) chip set operating at 20 Gb/s (5 Gb/s×4 ch) has been developed by using 0.25-μm CMOS technology. To achieve multichannel data transmission and high-speed operation, the chip set features: (1) circuits for compensating the phase difference between multiple RX chips, which is due to data skew resulting from different lengths of transmission cables, and for compensating the frequency difference between the system clocks of the TX and RX chips; (2) a self-alignment phase detector with parallel output for a high-speed data-recovery circuit; and (3) a fully pipelined 8B10B encoder. At a 2.5-V power supply, the power consumption of the TX chip during 5-Gb/s operation is 500 mW and that of the RX chip is 750 mW. Four of these TX/RX chip sets can provide an aggregate bandwidth of 20 Gb/s 相似文献

A 60-GHz cutoff frequency (fT) super self-aligned selectively grown SiGe-base (SSSB) bipolar technology is developed. It is applied to 20-Gb/s optical fiber transmitter ICs. Self-aligned bipolar transistors mutually isolated by using a BPSG-filled trench were fabricated on a bond-and-etchback silicon-on-insulator (SOI) substrate to reduce the collector-substrate capacitance CCS. The SiGe base was prepared by selective epitaxial growth (SEG) technology. A 0.4-μm wide emitter was used to reduce the junction capacitances. The maximum cutoff frequency fT and the maximum frequency of oscillation fmax were 60 and 51 GHz, respectively. By using this technology, Si-ICs for an optical transmitter system were made, such as a selector (a multiplexer without input and output retiming D-type flip-flops (D-F/Fs)), a multiplier, and a D-F/F. An internal high-speed clock buffer circuit achieves stable operation under a single clock input condition in the selector and the multiplier ICs. Their stable operation was confirmed up to 20 Gb/s. The selector IC for data multiplexing operates at over 30 Gb/s 相似文献

A BiCMOS programmable logic sequencer with a maximum operating frequency of 76 MHz at a power dissipation of 370 mW has been developed. The device is organized as 16 inputs, 48 product terms, and eight registered outputs. The excellent speed power performance and TTL/CMOS compatibility were realized by an optimized circuit design coupled with an advanced BiCMOS process. The process features 13-GHz bipolar transistors, 1- mu m CMOS, TiW fuses, poly resistors, three-layer metal, and single-layer polycide. Bipolar devices are used in areas that utilize their strengths such as high current drivers, small-signal sensing, and precise current sources. CMOS is used in other areas to conserve layout size and power.<> 相似文献

The authors introduce a two-port BiCMOS static random-access memory (SRAM) cell that combines ECL-level word-line voltage swings and emitter-follower bit-line coupling with a static CMOS latch for data storage. With this cell, referred to as a CMOS storage emitter access cell, it is possible to achieve access times comparable to those of high-speed bipolar SRAMs while preserving the high density and low power of CMOS memory arrays. The memory can be read and written simultaneously and is therefore well-suited to applications such as high-speed caches and video memories. A read access time of 3.8 ns at a power dissipation of 520 mW has been achieved in an experimental 4K×1-bit two-port memory integrated in a 1.5-μm 5-GHz BiCMOS technology. The access time in this prototype design is nearly temperature-insensitive, increasing to only 4 ns at a case temperature of 100°C 相似文献

In this paper, we highlight the effectiveness and flexibility of SiGe BiCMOS as a technology platform over a wide range of performance and applications. The bandgap-engineered SiGe heterojunction bipolar transistors (HBTs) continue to be the workhorse of the technology, while the CMOS offering is fully foundry compatible for maximizing IP sharing. Process customization is done to provide high-quality passives, which greatly enables fully integrated single-chip solutions. Product examples include 40-Gb/s (OC768) components using high-speed SiGe HBTs, power amplifiers compatible for cellular applications, integrated voltage-controlled oscillators, and very high-level mixed-signal integration. It is argued that such key enablements along with the lower cost and higher yields attainable by SiGe BiCMOS technologies will provide competitive solutions for the communication marketplace. 相似文献
