Abstract
An integrating A/D converter includes: a comparator comparing an input voltage to a reference voltage having a ramp waveform, a voltage value of which linearly varies with time; a higher-order bit counter starting operation or stopping operation triggered by inversion of an output signal of the comparator and outputting higher order bits by performing counting in a cycle of a clock signal; and a time-to-digital converter latching phase information of the clock signal corresponding to plural signals obtained by delaying an output signal of the comparator and decoding the latched values to output lower order bits having higher resolution than the clock cycle.
