Abstract
A digital clock generator circuit with built-in frequency and duty cycle control may include a pulse generator for generating a start pulse. The pulse generator may be connected to a ring oscillator to generate multiple signals having a specified frequency and programmable duty cycles. The oscillator may further be connected to a multiplexer which selectively connects one output of the ring oscillator to a final output to produce a signal of the specified frequency and specified duty cycle. The duty cycle may be adjustable over a wide range and across the full frequency band of operation.
