Abstract
A circuit for reducing the amount of instability in a pulse width modualtion circuit by providing a minimum amount of overdrive after the crossover point between a ramp and a voltage threshold level, and a constant amount of discharge time between the end on one ramp and the beginning of the next. Also, a feedback loop is privided to increase or decrease the slope to compensate for a decreasing or increasing amount of time between clock pulses, to maintain the duty cycle of the output when the clock frequency varies.
