Claim 19:
20. A digital-to-time convertor that receives an input signal and applies a delay corresponding to a control code to generate an output signal, the digital-to-time convertor comprising:
a slope generating circuit configured to generate a slope voltage, the slope generating circuit including a capacitor and a current source;
a precharge circuit configured to apply an analog voltage, determined based on the control code, to the control code to the capacitor;
a comparing circuit configured to compare the slope voltage with a threshold value and generate the output signal based on a comparison result; and
a control circuit configured to control the slope generating circuit and the precharge circuit based on the input signal and the output signal,
wherein the control circuit repeats the following operations:
turning on the precharge circuit during a precharge period;
transitioning to a slope period in response to transition of the input signal with the precharge circuit being off and the slope generating circuit being on during the slope period; and
turning off the slope generating circuit in response to transition of the output signal.
