A single MO-CFTA based electronically/temperature insensitive current-mode half-wave and full-wave rectifiers

Abstract

The article presents a current-mode full-wave rectifier employing multiple output current follower transconductance amplifier (MO-CFTA). The both circuits description is very simple, it merely comprises only single MO-CFTA, without external passive element. In addition, the magnitude and direction of output currents can be controlled via electronically method. Furthermore, the outputs are independent of the thermal voltage (VT). The performances of the proposed circuits are investigated through PSpice. They show that the proposed circuits can function as a current-mode precision half-wave and full-wave rectifiers where input current range from 0uA to 514uA and -518uA to 518uA, respectively. They can be achieved at ±2V power supplies. The maximum power consumption is 3,01mW.
