Minimum component high frequency current mode rectifier

Abstract

In this paper a current mode full wave rectifier circuit is proposed. The current mode rectifier circuit is implemented utilizing a floating current source (FCS) as an active element. The minimum component full wave rectifier utilizes only a single floating current source, two diodes and two grounded resistors. The extremely simple implementation enjoys high frequency operation and provides both inverting and non simultaneously. The rectifier system can work up to a frequency of 500MHz with acceptable distortion. The circuit exhibits low power consumption at ±0.75V supply voltage. The non-ideal and temperature analysis was also performed to study their impact on its performance. It was also shown that FCS can work as half wave rectifier as well. The performance of the circuit is evaluated using 0.18μm TSMC CMOS parameters using Hspice. ideal and temperature analysis was also performed to study their impact on its performance.
