Abstract
A digital-to-time converter (DTC) includes a plurality of delay stages connected in series, in which each of the plurality of delay stages includes an input circuit and a delay circuit. The input circuit has a first input terminal, a second input terminal and a first output terminal, and is configured to receive a clock signal through the first input terminal, receive a digital control signal through the second input terminal, generate an output signal according to the clock signal and the digital control signal, and output the output signal to the first output terminal of the input circuit. The delay circuit is coupled to the input circuit in series, and is configured to receive the output signal and an input signal, and generate a delay signal according to the output signal and the input signal. The delay signal indicates a time interval corresponding to the digital control signal.
