A ±5V Current Mode CMOS Four quadrant Analog Multiplier with High Frequency Capacity

A new current mode CMOS four quadrant analog multiplier consisted of two voltage controlled source coupled pairs is presented. The simulation results based on MOSIS 2μm p well CMOS process parameters show that under ±5V supply voltages and over ±4V input range, the nonlinear error is less than 0 9% and computation error is less than 1 0%;under the ±3V input range, the nonlinear error is less than 0 4% and computation error is less than 0 7%. The ±3dB bandwidth at Y input terminal is 130MHz, and, X input terminal, is 720MHz. The power dissipation is 4 90mW.
