Abstract: A charge pump of a phase-locked loop (PLL) circuit includes a current source circuit, a current sink circuit, and a biasing circuit. The biasing circuit includes a current digital-to-analog converter (IDAC) and a low-pass filter (LPF). The IDAC provides a reference current in response to a current value setting, wherein a first voltage is established due to the reference current. The LPF applies low-pass filtering to the first voltage to generate a filter output as a second voltage, wherein bias voltages of the current source circuit and the current sink circuit are controlled by the second voltage.
