A new high efficiency CMOS voltage doubler
Proceedings of CICC 97 - Custom Integrated Circuits Conference, 2002A charge pump cell is used to make a voltage doubler using improved serial switches. The PMOS transistor used for the serial switch is analyzed and a model suitable for simulation is described. The importance of capacitors is shown with plots of efficiency versus load and stray capacitance.

Phase Doubler for high power voltage regulators
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010As the power consumption of microprocessors increases, a high phase count voltage regulator is required to meet the power hunger (>180A) and high efficiency requirements. In general, the higher the phase number count, the more PWM outputs and current sensing inputs are required for the PWM controller.

Voltage doubler application in isolated resonant converters
31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005Two basic conditions of voltage-doubler adopted in isolated DC/DC converter are analyzed. According to the basic conditions, that voltage-doubler can be both adopted in LC series resonant converter and LLC multi-resonant converter. Operation characteristic of voltage-doubler adopted in isolated DC/DC converter is described in detail based on the ...

A low-voltage high-efficiency voltage doubler for thermoelectric energy harvesting
2013 IEEE International Conference of Electron Devices and Solid-state Circuits, 2013This paper presents a low-voltage high-efficiency voltage doubler for thermoelectric energy harvesting. A negative charge pump is used to reduce on-resistance of PMOSFET load switches. Additional circuitry for achieving high efficiency just requires small chip-area and low-cost. The voltage doubler is implemented in 0.13-μm 1.2V CMOS process.

Improved active‐diode circuit used in voltage doubler
International Journal of Circuit Theory and Applications, 2012SUMMARYAn improved active‐diode circuit, which makes use of positive feedback to achieve fast on/off transition, is presented in this paper. The proposed active‐diode circuit can be embedded into a voltage doubler to replace the commonly used dead‐time circuit and to eliminate reverse current. In addition, the relationship between oscillation frequency,

Performance Analysis of Multistage Voltage Doubler Rectifier for RF Energy Harvesting
2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019The conversion of electromagnetic energy into DC electrical energy is increasingly considered as the most appropriate solution to overcome the energy dependence of wireless sensor nodes (WSN). However, due to RF exposure limits, the output voltage levels

Design of a CMOS cross-coupled voltage doubler
2016 IEEE ANDESCON, 2016This paper describes a design procedure for a CMOS voltage doubler. Test-bench circuit are used to verify the performance of the design. Several equations that relate performance parameters with design variables are presented. This set of equations considers both transient and steady state behavior.
