Abstract
A method of operating a phase lock loop includes generating a control voltage based on both an output signal of a voltage-controlled oscillator and a reference signal. An operating mode is selected from one of a high-gain mode, a zero-gain mode and a low-gain mode based on the control voltage. The phase lock loop is operated in the selected one of the high-gain mode, the zero-gain mode, and the low-gain mode. The control voltage is offset to generate an offset voltage based on the selected operating mode. The output signal is generated based on the offset voltage.
