Minimum component high frequency current mode rectifier

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