Abstract

Keywords Pulse width Modulation (PWM), comparator, signal summation, voltage follower Background Pulse width modulation is a common technique used in voltage regulation. As customers demands for increased PWM performance has evolved they have required larger frequency compensation capacitors. Unfortunately these large compensation capacitors occupy a large portion of the semiconductor die resulting in increased die cost and reduced functionality per unit area. Therefore, it would be a competitive advantage to devise a circuit employing PWM having increased electrical performance, small die size and low capacitance.
