Abstract
A time-to-digital conversion circuit includes; an oscillator circuit that outputs a plurality of phase signals different from each other, a counter that counts a number of edges of at least one phase signal among the plurality of phase signals and outputs a count signal, a phase sampling circuit that samples the value of each of the plurality of phase signals at a stop time point and outputs a stop phase signal, a start phase signal generating circuit that outputs a start phase signal, and an output circuit that, based on the count signal, the stop phase signal, and the start phase signal, generates an output signal, the output signal being a digital signal indicating a time period from a start time point to a stop time point.
