Abstract

A simple structure of low-voltage current-mode CMOS analog multiplier circuit is presented. This multiplier circuit is based-upon quarter square algebraic identity technique by using CMOS technology. The transistors are operated in saturation region for different sub-circuits. The electronic resistor circuits are used as the input stage. The differential amplifiers are used for biased the squaring circuits. The current-mode operation can be obtained with a single supply, low-voltage, high-linearity and wide-bandwidth. This paper consists of 16 NMOSs with a 1.5 volts single supply. The achieved circuit performances have been carried out by PSpice. The input range is obtained more than plusmn100 muA with linearity error less than 1%. The frequency response can be operated larger than 150 MHz
