Low-voltage four-quadrant analog multiplier
38th Midwest Symposium on Circuits and Systems. Proceedings, 2002A novel design method for four-quadrant analog multiplier is presented. This method uses two current-mode maximum selecting circuits to combine the output currents of two MOS square-based multiplier cells. The proposed scheme nearly doubles the input voltage range.

High boost converter using voltage multiplier
31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005With the increasing demand for renewable energy, distributed power included in fuel cells have been studied and developed as a future energy source. For this system, a power conversion circuit is necessary to interface the generated power to the utility.

A Direct-Current Voltage Multiplier
Review of Scientific Instruments, 1936A device for obtaining a higher d.c. potential from a d.c. source is described. A number of condensers are connected permanently in series and charged successively by rotating brushes. The output voltage is shown to be quite steady under normal operating conditions. Equations for the output voltage and voltage fluctuation are derived.

Voltage efficiency of Schenkel type voltage multiplier circuit
Nuclear Instruments and Methods, 1969Abstract The Schenkel type voltage multiplier circuit cannot be divided into four-terminal networks. Therefore the transmission line theory, by the aid of which the voltage efficiency for the Cockcroft-Walton type voltage multiplier circuit is obtained, cannot be applied directly.

Ultra low voltage current multiplier/divider
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003In this paper we present novel current-mode multiplier/divider circuits utilizing the features of FGUVMOS transistors. Even for ultra low supply voltages a proper operation is achieved with threshold shifting using post-fabrication tuning. Measured results are provided of a multiplier working over a large magnitude in current at 0.7 V power supply.

Useful multipliers for low-voltage applications
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003Two useful low voltage multipliers are presented in this paper. They employ only two transistors between the rails and perform four-quadrant multiplication. These circuits are based on the V/sub gs//sup 2/ technique, and use MOS transistors in saturation in order to achieve squaring of the differential inputs.

A 1.5 V CMOS voltage multiplier
1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002New and simple CMOS multiplier powered with a 1.5 V supply is presented. It has a 3-dB cut-off frequency at 140 MHz, and reaches its 1-dB compression point for 140 mV/sub pp/ of input voltage. Moreover, its particular topology makes it useful for an integration in fully digital ICs.

Voltage-mode threshold-independent analogue multiplier
International Journal of Electronics, 2009In this article, a new threshold-independent four-quadrant analogue multiplier is designed and developed. It is based on the square-law of the MOS transistor in the saturation region and quarter-square algebraic identity. The circuit structure uses voltage summing and voltage-mode squaring stages.

Interleaved resonant switched capacitor voltage multiplier
2018 International Conference on Electronics, Communications and Computers (CONIELECOMP), 2018In this paper we present an interleaved switched capacitor voltage multiplier with resonant-type current between capacitors. The proposed converter features are: step up gain, low input current ripple, soft switching, and modular structure without using energy storage inductors.
