Abstract
An oscillator with oscillator and voltage control circuitry for generating an oscillation signal having an amplitude that is automatically controlled for a selectively minimized phase noise. Automatic level control is used for controlling the amplitude of the oscillation signal such that the phase noise of the oscillation signal can be maintained at some selected level, e.g., minimized. The minimum signal voltage appearing across the oscillation circuit is monitored for controlling the bias of the circuit to prevent it from entering a saturation state, thereby avoiding adverse loading effects responsible for degraded phase noise performance.
