A Counter-Based DPWM Device with Resolution Extension

Abstract:

Counter-based Digital PWM (DPWM), the simplest DPWM device, can be easily implemented only by a counter and a comparator; however, the resolution of the counter-based DPWM is directly proportional to its input reference clock, and thus the higher clock frequency is required, which means higher dynamic power consumption and noise interference may be incurred. In this paper, without increasing the reference clock frequency, a new design approach using capacitor integration is proposed to extend the resolution of the counter-based DPWM, and it also can reduce the hardware complexity compared with the delay-line DPWM.
