Abstract

According to one embodiment, a multi-bit delta-sigma time digitizer circuit includes a delay array including delay selection circuits respectively including a delay element and a multiplexer, a phase comparator calculating a time difference, an integrator integrating the time difference output, a flash A/D converter executing digital conversion, a ring oscillation circuit including the delay array, a counter measuring a number of clock signal pulses, a memory storing a delay value of the delay element, and a processor correcting an output result of the A/D converter based on the delay value when the rising timing interval is measured.
