Abstract
A device is disclosed that includes a delay circuit, a detection circuit, and a bias circuit. The delay circuit is configured to generate an oscillating signal in response to a reference signal, a first bias voltage, and a second bias voltage. The detection circuit is configured to compare the oscillating signal with the reference signal, to generate a detect signal. The bias circuit is configured to adjust the first bias voltage and the second bias voltage according to the detect signal and a reference voltage.
