Abstract
A pulse-width modulation circuit includes an oscillator stage. The oscillator stage includes a first voltage comparator having a first input terminal, a second input terminal and an output terminal. A first capacitor is coupled to the first input terminal of the first voltage comparator. A charging path for the first capacitor is coupled between the first capacitor and the output terminal of the first voltage comparator, the charging path having a first resistance. A discharging path for the first capacitor is coupled between the first capacitor and the output terminal of the first voltage comparator, the discharging path having a second resistance that is different from the first resistance. A duty cycle of a clock signal generated by the oscillator stage is determined based on a first RC time constant for charging the first capacitor and a second RC time constant for discharging the first capacitor.
