Abstract
An integrated circuit includes a delay lock loop (DLL) circuit that generates incremental delay line signals and a delay line output signal based on a received clock signal. A pulse-width modulation (PWM) control module generates a PWM control signal. A tunable circuit having variable capacitance is controlled based on the delay line output signal, the PWM control signal, and one of the incremental delay line signals.
