Abstract
A high resolution pulse width modulation (PWM) or voltage controlled output (DCO) generator is disclosed. The resolution is increased over that of the circuit clock by delaying the generated signal through a series of delays, all of which are controlled by a delay locked loop. The delays are a small fraction of the clock period, thus providing resolution greater than that of the circuit clock.
