Claim 9:
10. An analog-to-digital converter circuit converting an input analog signal to a digital signal and outputting the digital signal, the analog-to-digital converter circuit comprising:
the time-to-digital converter according to claim 6;
a sample and hold circuit sampling and holding a voltage of the analog signal;
a reference-waveform-signal generator circuit generating a reference waveform signal based on the reference signal; and
a comparator comparing the voltage held by the sample and hold circuit with a voltage of the reference waveform signal and outputting the trigger signal,
the analog-to-digital converter circuit outputting the digital signal based on the time-digital value calculated by the time-to-digital converter.
