Abstract
A time to digital conversion circuit includes a pulse signal generator configured to generate a pulse signal in response to activation of a transition detection signal, a latch circuit configured to latch a multiphase clock signal in response to a trailing edge of the pulse signal, an upper time to digital converter (TDC) configured to latch, in response to activation of a timing signal, a code whose value changes at the same period as a period of the multiphase clock signal, and a synchronization circuit. The latch circuit forms a lower TDC. The synchronization circuit supplies a signal synchronized by receiving the transition detection signal at a timing decided in accordance with a signal generated by the lower TDC as the timing signal to the upper TDC.
