摘要： In a time measuring circuit, a pulse delay circuit is provided with a plurality of delay units. The pulse delay circuit is configured to transfer a pulse signal through the plurality of delay units while the pulse signal is delayed by the plurality of delay units. A delay time of each of the plurality of delay units depends on a level of a first drive voltage being input to each of the plurality of delay units. A generating circuit is configured to obtain a number of the delay units through which the pulse signal has passed within a predetermined period to generate, as time measurement data, digital data based on the obtained number. A first setting unit is configured to variably set the level of the first drive voltage being input to each of the plurality of delay units.
