Abstract: An AD converter converting an inputted analog signal into a digital signal is provided with an integrator outputting integrated waveforms obtained by sequentially integrating a signal level of the analog signal, a digital converting part detecting transition timing when a size relation of the signal level of the integrated waveform and a prescribed reference value transits to a prescribed state with prescribed time resolution, a feedback part controlling the signal level of the integrated waveform in accordance with a detection result in the digital converting part at a control period larger than time resolution, and a signal processing part generating the digital signal based on the detection result in the digital converting part.
