Quadratic-translinear CMOS multiplier-divider circuit

Abstract

A novel current-mode analogue multiplier-divider based on the quadratic-translinear principle is presented. The input and output signals are all in current-mode. The circuit has favourable precision, wide dynamic range and is insensitive to variations in temperature and processing. It is suitable for VLSI implementation and can be used in many hardware design fields such as fuzzy logic controllers and analogue neural networks.
