— A digitally controlled current starved pulse width modulator (PWM) is described in this paper. The current from the power grid to the ring oscillator is controlled by a header circuit. By changing the header current, the pulse width of the switching signal generated at the output of the ring oscillator is dynamically controlled, permitting the duty cycle(More)
A digitally controlled pulse width modulator (PWM), targeting on-chip power management applications is proposed in this paper. A current starved ring oscillator, with digitally controlled current source based headers and footers, is used to provide a versatile duty cycle and an accurate frequency control. The proposed circuit achieves i) a controlled duty(More)
