A low-power pulse width modulation (PWM) control circuit for high-frequency switching direct current (DC)–DC converters based on a one-shot circuit is proposed. The proposed PWM control circuit eliminates the use of a high-power comparator and ramp generator that is conventionally used to generate the PWM waveform. The design is validated through simulation in a 0.13-μm process. The proposed circuit operating at 20 MHz demonstrates greater than 20× reduction in power consumption compared with the conventional PWM circuit over a duty-cycle range of 10–90%.
