Four quadrant analogue CMOS multiplier using capacitively coupled dual-gate transistors

A small area, wide dynamic range, four quadrant analogue CMOS multiplier is presented, based on capacitively coupled dual-gate (CCDG) MOSFETs. Models are developed, and the multiplier is simulated with these models. The properties and advantages of the CCDG MOSFET in multipliers are shown, also by comparison with an existing multiplier.
