A novel four-quadrant analog multiplier using laterally nonuniform gate voltage MOSFET

A four terminal MOSFET with gate voltage nonuniformly distributed along the channel (LNUGV) was analyzed recently by the author and was found to be capable of performing first-quadrant multiplication operation in a single device, making them inherently superior to multistage multiplier circuits currently used in communication and analog VLSI circuits. Fully active two-quadrant and four-quadrant analog multiplier circuits, using identical n-channel LNUGV-MOSFETs as core transconductors, operating in enhancement mode, saturation regime and within specific ranges, are presented in this paper.
