Abstract
A phase-locked loop (PLL) includes a voltage-controlled oscillator (VCO) that generates a PLL output signal having an oscillation frequency controlled by a control signal; a phase detector that generates a phase signal representing a difference in phase between the PLL output signal and a reference signal; a loop filter coupled to receive the phase signal; a switch; and a sampling circuit switchably coupled to receive the control signal of the VCO via the switch, and generating a code representing the control signal.
