A Study and Comparison of Low Voltage CMOS Current Multiplier

A study and comparison between current mode CMOS analog multiplier, CMOS current mode multiplier/divider and high frequency four quadrant current multiplier has been carried out in this paper. Current multiplier has been simulated in SPICE with 0.35μm, 0.5µm. Simulation have been done with supply voltage of 3.3V, 1.5V and 1.55V respectively. The simulated results show that characteristic of multipliers are linear with 10μA, 10μA and 30μA input range respectively. These circuits are widely used for analog signal processing application.
