Abstract
A clock data recovery (CDR) circuit includes a phase detector circuit, a proportional path, an integral path, and an oscillator circuit. The phase detector circuit is configured to receive input data and detect the input data based on an oscillation signal to output a detection result. The proportional path is configured to output a proportional control signal based on the detection result. The proportional path includes a charge pump circuit and a variable capacitor. The charge pump circuit generates a voltage control signal based on the detection result. The variable capacitor generates the proportional control signal based on the voltage control signal. The integral path is configured to output an integral control signal based on the detection result. The oscillator circuit is coupled to the proportional path and the integral path and configured to generate the oscillation signal based on the proportional control signal and the integral control signal.
