Abstract
A current source suitable for use as a loop filter in a phase-locked loop having two aspects of automatic gain control one for prohibiting the voltage controlled oscillator from stopping as the input voltage approaches the limits of the oscillator and another to compensate for current limiting drain to source voltage drops.
