Phase-locked loop oscillator with loop gain compensation
A phase-locked loop oscillator with loop gain compensation. The phase-locked loop oscillator includes a phase comparator, a loop filter, a voltage-controlled oscillator, a control device, and a variable-gain amplifier disposed between the phase comparator and the loop filter. The oscillator detects the output signal voltage of the loop filter and controls the amplification rate of the variable-gain amplifier so that the loop gain is compensated and held constant, without sacrificing continuity.
