Abstract

A new CMOS current-mode four-quadrant analog multiplier is presented. The design is based on the square-difference approach using short-channel MOSFETs operating in saturation region and a rectifier. The squaring circuit used is free of error due to carrier mobility reduction and hence an accurate multiplier is achieved. Tanner T-spice is used to confirm the functionality of the proposed design using 0.18μm TCMS CMOS process technology. Simulation results shows that the relative error is 1.8% and –3dB frequency is 230MHz.
