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 ...

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

Flyback battery equalizer with voltage doubler rectifier
8th International Conference on Power Electronics - ECCE Asia, 2011In this paper, a new flyback battery equalizer employing a voltage doubler rectifier is proposed. The proposed circuit transfers electric charges by utilizing the resonance between the transformer leakage inductor and secondary capacitor. Therefore, the proposed battery equalizer can reduce the switch turn off loss and snubber loss by a sinusoidal ...

A power factor correction with voltage doubler rectifier
2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002For small capacity rectifier circuits with a small capacity, such as those for consumer electronics and appliances, capacitor input type rectifier circuits are generally used. Consequently, various harmonics generated within the power system become a serious problem. Various studies of this effect have been presented previously so far. However, most of
