Abstract

See full text

In an example, a system includes a phase-locked loop including a charge pump coupled to a phase frequency detector, a low-pass filter coupled to the charge pump, and a VCO coupled to the low-pass filter, where the charge pump is configured to provide a charge pump current to the low-pass filter. The system also includes a current source configured to provide a bias current to the charge pump. The system includes a first bias compensation circuit configured to increase the bias current responsive to a control voltage provided to the VCO being within a first range. The system also includes a second bias compensation circuit configured to decrease the bias current responsive to the control voltage provided to the VCO being within a second range.
