A Novel Hybrid DPWM for Digital DC-DC Converters
一种适用于DC-DC变换器的新型混合式数字脉宽调制器

We present a new hybrid digital pulse-width modulator(DPWM) for digital DC-DC converters that employs a ring-oscillator/counter structure.Based on a temperature/process compensation technique and a novel digital controller,the proposed DPWM can not only offer temperature/process-independent pulse widths,but also operate at a much higher clock frequency than the existing delay-line/counter DPWM structure.Post-simulation results show that with our DPWM,the system clock frequency reaches 156.9MHz while the wor...
