Analysis of Voltage Doubler Behavior of 2.45-GHz Voltage Doubler-Type Rectenna
IEEE Transactions on Microwave Theory and Techniques, 2017This paper describes the voltage doubler (VD) behavior of a 2.45-GHz VD-type rectenna. An important feature of the developed VD-type rectenna is the absence of the charge pump capacitor that is present in conventional VDs. Based on the circuit simulation and measurement results, the developed VD-type rectenna shows drastic improvement to the radio ...

A Step-Up DC–DC Converter With a Resonant Voltage Doubler
IEEE Transactions on Industrial Electronics, 2007A step-up dc-dc converter with a resonant voltage doubler is proposed. The proposed converter is composed of an active-clamp circuit and a resonant voltage doubler. The active-clamp circuit, which is controlled by dual asymmetrical pulsewidth modulation of the primary side, reduces the voltage spikes of main switches and limits the voltage stress of ...

A voltage-sensorless PFC voltage doubler
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012This paper proposes a voltage-doubling rectifier, or voltage doubler, with power factor correction (PFC) function and without voltage sensors on the ac and dc sides. The rectifier only uses an ac-side current sensor. The voltage information required for the PFC control is obtained from the ac-side current and its derivative in the on and off durations ...

A breakdown voltage doubler for high voltage swing drivers
Proceedings of the IEEE 2004 Custom Integrated Circuits Conference (IEEE Cat. No.04CH37571), 2004A novel breakdown voltage (BV) doubler is introduced that makes it possible to generate high output voltage swings using transistors with low breakdown voltages. The timing analysis of the stage is used to optimize its dynamic response. A 10 Gb/s optical modulator driver with a differential output voltage swing of 8 V on a 50 /spl Omega/ load was ...

Design of Maximum-Efficiency Integrated Voltage Doubler
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007In this paper, an algorithm and the analytical expressions to be used for the design of maximum-efficiency integrated charge pumps based on the voltage doubler architecture are presented. Starting from basic considerations on charge transfer, the proposed methodology allows adequate choice of the stage number and of the size of all charge pump elements,

A Low Ripple Current Mode Voltage Doubler
2015 IEEE 18th International Symposium on Design and Diagnostics of Electronic Circuits & Systems, 2015Experimental results of a fully integrated low ripple charge pump voltage converter are presented. The pump is a current mode voltage doubler with a novel parasitic capacitance precharge mechanism for output voltage ripple reduction. A prototype of the pump was designed and fabricated in 130 nm CMOS process.

A low-voltage voltage doubler without body effect
2008 9th International Conference on Solid-State and Integrated-Circuit Technology, 2008A voltage doubler, which avoids body effect and then improves rise time and efficiency even with 1 V power supply, is presented. This art is designed for word line boosting, using 0.18 um EEPROM technology. Not only the voltage doubler can work with capacitive load normally, but also it can supply load current and achieve higher efficiency.

Yield optimization of a RSFQ voltage doubler
Journal of Low Temperature Physics, 1997The centers-of-gravity optimization method has been applied to optimize a complex circuit consisting of a dc/SFQ-converter and RSFQ voltage doubler in order to obtain maximum parameter margins. As a result, the margins of all circuit parameters have been enlarged to at least ±35%. This improves the yield of the circuit fabrication process. On the other
