Abstract
A high-frequency voltage controlled oscillator includes a start-up circuit for preventing the oscillator from enering a stable state and that does not increase the fixed delays in the oscillator feedback paths. A sleep mode feature shuts down the oscillator to conserve power and capacitors are used to isolate the oscillator from high-frequency noise coupled through the power supply inputs.
