Abstract :
A wide-band precision CMOS half-wave rectifier circuit with positive and negative outputs is presented, in this paper. The proposed circuit consists of a voltage-to-current converter, a precision current-mode rectifier with operating in class AB, and two current-to-voltage converters. A voltage input signal is changed into a current signal by the voltage-to-current converter. The class AB current-mode rectifiers rectify these current signals, resulting in positive and negative half-wave current signals that are converted to positive and negative half-wave voltage signals by the current-to-voltage converters. The circuit exhibits low component counts, high frequency operation, good temperature stability and suitable of IC fabrication. The simulation results are used to verify the performance of the proposed circuit. Simulated rectifier performance with standard 0.5¿m CMOS technology using ±1.2 V supply voltage shows the proposed half-wave rectifier circuit provides an operating frequency more than 250 MHz and excellent temperature stability.
