Abstract
In this paper, we have proposed and realized a novel precision full-wave rectifier using an all-pass filter as a 90° phase shifter. The circuit gives a dc output voltage that is almost the same as the peak input voltage over a frequency range of 50 Hz-1 MHz with a very low ripple voltage and low harmonic distortion. Oscilloscope traces of the rectified waveform for the proposed circuit show a ripple voltage of 12 mV obtained with an input voltage of amplitude 1 V and frequency 100 kHz.
