Abstract
In this paper, a new current squarer and precision full-wave rectifier based on a CMOS class AB amplifier that modified to receive a differential input current has been presented. The proposed circuits are simulated with HSPICE level 49. From a ±1.5 V supply voltage, the power consumption of the rectifier and the squarer at the quiescent point are about 210nW and 120 μW, respectively. The total harmonics distortion of the squarer is less than 1%, with a input signal of 24 μA.
