Abstract

In this work, we present a four-quadrant CMOS current-mode multiplier based on the square-law characteristics of an MOS transistor operated in the saturation region. One advantage of this multiplier is that the output current is independent of MOS transistor device parameters; another, that the input resistance is independent of the input current. Simulations of the multiplier demonstrate a linearity error of 1.22%, a THD of 1.54%, a -3 dB bandwidth of 22.4 MHz, and a maximum power consumption of 0.93 mW. Operation of the multiplier was also confirmed through an experiment using CMOS 4007 IC´s
