A low-power 16:1 multiplexer (MUX) IC using undoped-emitter InP/InGaAs heterojunction bipolar transistors (HBTs) has been successfully designed and fabricated. To minimise power consumption, the collector current density of each HBT was optimised taking into account the required operating speed and the number of fan-outs. Up to 47 Gbit/s error-free operation was confirmed with low power consumption of about 3.2 W. These results demonstrate that InP/InGaAs HBT technology is attractive for fabricating over 40 Gbit/s, low-power medium-scale-integration (MSI) circuits. 相似文献

In this paper, a monolithically integrated clock and data recovery (CDR) circuit with 1:2 demultiplexer (DEMUX), which is intended for use in 80 Gbit/s optical fiber links, is presented. The integrated circuit (IC) is manufactured using an in-house InP double heterostructure bipolar transistor (DHBT) technology, exhibiting cut-off frequency values of more than 220 GHz for both$f_T$ and$f_max $ . The CDR circuit in the topology of a phase-locked loop (PLL) is mainly composed of a half-rate linear phase detector including a 1:2 demultiplexer (DEMUX), a loop filter, and a voltage-controlled oscillator (VCO). Hence, the corresponding architecture of each of these components as well as the applied circuit design technique are extensively addressed. Concerning the performance achieved by the CDR/DEMUX IC, the recovered and demultiplexed 40 Gbit/s data from an 80 Gbit/s input signal feature clear eye opening with a signal swing as high as 600$hboxmV_ pp$ . The extracted 40 GHz clock signal shows a phase noise as low as$- hbox98~dBc/hboxHz$ at 100 kHz offset frequency. The corresponding rms jitter amounts to 0.37 ps while the peak-to-peak jitter is as low as 1.66 ps. At a single supply voltage of$-hbox4.8~V$ , the power consumption of the full CDR/DEMUX IC amounts to 1.65 W. To the authors' best knowledge, this work demonstrates the first CDR circuit at the achieved data rate, regardless of all the competing semiconductor technologies. 相似文献

Using InP-InGaAs heterojunction bipolar transistor (HBT) technology, we have successfully designed and fabricated a low-power 1:16 demultiplexer (DEMUX) integrated circuit (IC) and one-chip clock and data recovery (CDR) with a 1:4 DEMUX IC for 10-Gb/s optical communications systems. The InP-InGaAs HBTs were fabricated by a nonself-aligned process for high uniformity of device characteristics and producibility. The 1:16 DEMUX IC and the one-chip CDR with the 1:4 DEMUX IC consist of approximately 1200 and 460 transistors, respectively. We have confirmed error-free operation at 10 Gb/s for all data outputs of both ICs. The 1:16 DEMUX IC and the one-chip CDR with the 1:4 DEMUX IC consume only 1 W and 950 mW, respectively. These results demonstrate the feasibility of InP-InGaAs HBTs for low power high-integration optical communication ICs. 相似文献
