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 210 nW and 120 μW, respectively. The total harmonics distortion of the-squarer is less than 1%, with a input signal of 24 μA.
