Abstract: To provide a time measuring apparatus which is compact and capable of highly accurate measurements, on a semiconductor chip, DFF circuits F10 through F1f constituting a delayed-signal holding circuit 11 of channel CH1 and DFF circuits F20 through F2f constituting a delayed-signal holding circuit 21 of channel CH2 are disposed alternatingly and in a single row in a circuit region of the delayed-signal holding circuits 11 and 12 to latch delayed signals DY0 through DYf from a pulse-circulating circuit 4, and DFF circuits F1j and F2j (where i = 0 through 9 and a through f) to latch the same delay signals DYj are mutually adjacent. Due to this, distances between the pulse-circulating circuit 4 and the respective delayed-signal holding circuits 11 and 12 become equal, and delay signals DY0 through DYf having no deviation in delay due to difference in wiring length are supplied to the respective channels, and so uniform measurement can be performed between the respective channels.

Abstract: A pulse circulating circuit includes inverting circuits each for inverting an input signal and outputting an inversion of the input signal. A time of signal inversion by each of the inverting circuits varies in accordance with a power supply voltage applied thereto. One of the inverting circuits constitutes an inverting circuit for starting which is controllable in inversion operation. The pulse circulating circuit circulates a pulse signal therethrough after the inverting circuit for starting starts to operate. An input terminal subjected to an analog voltage signal is connected to power supply lines of the respective inverting circuits for applying the analog voltage signal to the inverting circuits as a power supply voltage fed thereto. A counter serves to count a number of times of complete circulation of the pulse signal through the pulse circulating circuit. A circulation position detecting device serves to detect a circulation position of the pulse signal in the pulse circulating circuit on the basis of output signals of the respective inverting circuits. A control device is operative for activating the inverting circuit for starting and thereby starting pulse circulating operation of the pulse circulating circuit, and for activating the circulation position detecting means at a moment which follows a moment of starting pulse circulating operation by a given time. An output device is operative for outputting digital data as an A/D conversion result. The A/D conversion result data has lower bits composed of output digital data of the circulation position detecting device, and higher bits composed of output digital data of the counter.
