摘要
This paper presents a single low-voltage CMOS analog multiplier with high-linearity, low total harmonic distortion and low-power consumption. It consists of four voltage adders, four nullors and a multiplier core. The proposed circuit is simulated with HSPICE and simulation results have shown that, under single 1V supply voltage, the circuit has smaller than 0.65% linearity error and 0.36% THD under the maximum-scale input 400mVp-p at both inputs. The quiescent power consumption is 120 mu W and the -3dB bandwidth is 30MHz.
