Abstract
This paper presents a pulse width modulator (PWM) circuit using single operational transconductance amplifier. In this technique the pulse width of the PWM is controlled using a scheme, wherein the modulating signal is added with an exponential carrier waveform and compared with thresholds. SPICE simulation and experimental results are presented in order to validate the theory.
