Design of a CMOS low-power and low-voltage four-quadrant analog multiplier

摘要

A New CMOS four-quadrant analog multiplier is presented in this paper. The proposed multiplier is suitable for low supply-voltage operation and its power consumption is also very low. The proposed circuit has been simulated with the HSPICE and simulation results are given to confirm the feasibility of the proposed analog multiplier. According to the simulation results, under the supply voltage of 1.5 V, the input range of the proposed multiplier can be 120 mV and the corresponding maximum linearity error is less than 3.2%. Moreover, the power dissipation of the proposed circuit is only 6.7 μW. The proposed circuit is expected to be useful in analog signal processing applications.
