A study and comparison between current mode CMOS analog multiplier, ±1.5 V High frequency four quadrant current multiplier and ±1.2 V High frequency four quadrant current multiplier has been carried out in this paper. Current multiplier has been si mulated in SPICE with 0.35?m and 0.5? m technology. Simulation has been done with supply voltage of 3.3V,1.5V and 1.2V respectively. The simulated results show that characteristic of multipliers are linear with 10?A, 30?A and 20?A input range respectively and power dissipation of ±1.2 V High frequency four quadrant current multiplier is less as compared to the other circuits in 0.35 ?m and 0.5 ?m technology. These circuits are widely used for analog signal processing application.
