Summary: 
In this paper, a four-quadrant analog multiplier consisting of four neuron-MOS transistors and two load resistors is proposed. The proposed multiplier can be operated at only 1 V. Furthermore, the input range of the multiplier is equal to 100% of the supply voltage. The theoretical harmonic distortion caused by mobility degradation and device mismatchs is derived in detail. The performance of the proposed multiplier is characterized through HSPICE simulations with a standard 2.0 µm CMOS process with a double-poly layer. Simulations of the proposed multiplier demonstrate that the linearity error of 0.77% and a total harmonic distortion of 0.62% are obtained with full-scale input conditions. The maximum power consumption and 3 dB bandwidth are 9.56 µW and 107 MHz, respectively. The active area of the proposed multiplier is 210 µm 140 µm.
