Abstract
A phase-locked loop (PLL) circuit includes a voltage-controlled oscillator configured to generate an output clock signal of the PLL circuit, a phase detector configured to generate a phase error signal representing a phase difference between a first clock signal based on a reference clock signal and a second clock signal based on the output clock signal, a comparator configured to generate a phase error sign signal based on a reference voltage and the phase error signal, and a reference voltage generation circuit configured to scale first and second sign values of the phase error sign signal based on a fixed gain value and a variable gain value, respectively, and generate the reference voltage based on the scaled first and second sign values.
