Abstract

A low-voltage low-power integrated pulse-width-modulation (PWM) circuit using CMOS processes is presented in this paper. The proposed PWM circuit only consists of CMOS transistors and can be implemented with digital CMOS processes without extra internal or/and external passive components. In the proposed circuit, the curve-compensation technique is used to achieve approximately constant frequency operation. This circuit will be useful in low-voltage multimedia circuit, power electronic and telecommunication applications.
