Abstract
Applications like signal detectors and sample and hold circuits in communication are dependent on low-voltage rectification. Normally, a diode is used as a rectifier having the drawback of rectification at a voltage below its threshold voltage. Here, the authors have proposed a new technique of full wave rectification without diodes operating at low input voltage and implemented on a printed circuit board. The circuit gives a dc output voltage almost same as peak input voltage with low harmonic distortion. The oscilloscope trace shows the output signal ~98 mV with ripple voltage 1 mV obtained with input voltage of amplitude, 100 mV at frequency 100 kHz.
