Abstract
A pulse-width modulation (PWM) circuit includes a partition circuit coupled to receive a PWM value representing a duty cycle of a PWM signal to be generated, and configured to accordingly generate a most-significant-bits (MSB) value representing higher-order bits of the PWM value and a least-significant-bits (LSB) value representing lower-order bits of the PWM value; a PWM generator coupled to receive the MSB value or a derivative thereof, and configured to accordingly generate a primary signal with a duty cycle corresponding to the MSB value; a delay circuit that generates a delay signal representing the primary signal with delay time determined according to the LSB value or a derivative thereof; and a combine circuit that generates the PWM signal according to the primary signal and the delay signal, by performing a logical operation on the primary signal and the delay signal.
