A new inverter-based charge pump circuit with high conversion ratio and high power efficiency

The current paper presents a new inverter-based charge pump circuit with high conversion ratio and high power efficiency. The proposed charge pump, which consists of a PMOS pass transistor, inverter-based switching transistors, and capacitors, can improve output voltage and conversion ratio of the circuit. The proposed charge pump was fabricated with TSMC 0.35 μm 2P4M CMOS technology. The chip area without pads is only 0.87 mm×0.65 mm. The measured results show that the output voltage of the four-stage charge pump circuit with 1.8 V power supply voltage (V_DD=1.8 V) can be pumped up to 8.2 V. The proposed charge pump circuit achieves efficiency of 60% at 80 μA.     

A new power converter for fuel cells with high system efficiency

This paper presents a new high-efficiency grid-connected single-phase converter for fuel cells. It consists of a two-stage power conversion topology. Since the fuel cell operates with a low voltage in a wide voltage range (25?V–45?V) this voltage must be transformed to around 350–400?V in order to be able to invert this dc power into ac power to the grid. The proposed converter consists of an isolated dc–dc converter cascaded with a single-phase H-bridge inverter. The dc–dc converter is a current-fed push-pull converter. The inverter is controlled as a standard single-phase power factor controller with resistor emulation at the output. Experimental results of converter efficiency, grid performance and fuel cell dynamic response are shown for a 1?kW prototype. The proposed converter exhibits a high efficiency in a wide power range (higher than 92%) and the inverter operates with a near-unity power factor and a low current THD.     

Obtaining high efficiency at low power using a quantum-dotmicrocavity light-emitting diode

Efficiencies are calculated for quantum-dot apertured-microcavity light-emitting diodes. Although the maximum efficiency depends strongly on the quantum-dot inhomogeneous broadening, greater than 20% efficiency is calculated for a small-sized apertured microcavity, even for an inhomogeneous linewidth as large as 30 meV. The efficiency can be increased to 40% if the inhomogeneous linewidth is reduced to 10 meV and to more than 60% if the inhomogeneous linewidth is eliminated to leave a homogeneous linewidth of 6.6 meV. The maximum output powers are ~40 nW, although a microarray can increase this value. For the case of a single quantum dot, an efficiency >80% is estimated for a submicron apertured-microcavity, with a maximum output power of ~3 nW

关注业务、关注效率、关注安全--中科新业互联网安全审计系统

如何保障一切基于网络的社会活动的正常运作渐渐成为整个互联网行业内的焦点问题,社会一方面需要通过网络加速信息传递,提高生产力以及工作效率,另一方面又希望避免因互联网固有的开放与自由性,以及各种层出不穷的、形形色色的网络活动所带来的非安全及不稳定因素所造成的危害。从现实的角度来分析,这两点本身具有相当程度的对立性:信息快速高效传递的基础就是互联网所具有的开放性和自由性,而这本身又会具有很多安全隐患,并由此影响到生产力的提高。这是每个互联网的使用者所不愿看到的。 为了解决上述问题,人们不断研究各种网络安全防御技…     

ILNP: mobility, multi-homing, localised addressing and security through naming

Internet users seek solutions for mobility, multi-homing, support for localised address management (i.e. via NATs), and end-to-end security. Existing mobility approaches are not well integrated into the rest of the Internet architecture, instead primarily being separate extensions that at present are not widely deployed. Because the current approaches to these issues were developed separately, such approaches often are not harmonious when used together. Meanwhile, the Internet has a number of namespaces, for example the IP address or the Domain Name. In recent years, some have postulated that the Internet’s namespaces are not sufficiently rich and that the current concept of an address is too limiting. One proposal, the concept of separating an address into an Identifier and a separate Locator, has been controversial in the Internet community for years. It has been considered within the IETF and IRTF several times, but always was rejected as unworkable. This paper takes the position that evolving the naming in the Internet by splitting the address into separate Identifier and Locator names can provide an elegant integrated solution to the key issues listed above, without changing the core routing architecture, while offering incremental deployability through backwards compatibility with IPv6.     

A low noise,high power efficiency supply regulator for near-field power delivery

In order to deliver near-field electromagnetic power to a biomedical device or an RFID tag efficiently, the downlink signal is preferred to be at a high voltage level. To reduce power consumption and meet low supply requirements, it is advantageous for the remote device power supply to step-down the input voltage following rectification, typically using switch-mode regulators. The output ripple of a switched capacitor converter is inversely proportional to the filtering capacitance at the output node and switching frequency. In this paper, a hybrid DC–DC converter utilizing a switched capacitor regulator in master–slave configuration with a linear regulator is presented. Linear regulator actively cancels the switching ripple, while low frequency and DC current is provided by the switched capacitor converter. The converter is designed to receive an average input voltage of 5 Vpk from the receiver coil, with an output voltage of 2 V, and 5 mA of output current. The proposed regulator is fabricated in 0.35 μm technology. The power efficiency is measured to be 67%, with a nominal peak to peak ripple of less than 2 mV at the output.     

A 2.4 GHz high output power and high efficiency power amplifier operating at inductive breakdown in CMOS technology

In this paper, a novel CMOS power amplifier (PA) with high output power and power added efficiency is designed to operate in the avalanche region by increasing the supply voltage for the first time. With the X-parameter measurement based poly-harmonic distortion (PHD) behavioral model including the X^S and X^T terms, the simulation results can reveal accurate large signal characteristics of the whole PA at breakdown. The output power at 1-dB compression point of 30.2 dBm with 34.1% PAE at 2.4 GHz is obtained.
