Abstract
A pulse detection circuit according to an embodiment includes a conversion circuit, a delay circuit, first and second comparators, a latch, and a generation circuit. The conversion circuit converts an input signal into a thermometer code signal. The delay circuit outputs a delay signal being the thermometer code signal delayed by a predetermined delay time. The first comparator (The second comparator) compares the thermometer code signal with the delay signal and outputs an increase signal (a decrease signal) indicating whether the input signal is larger (smaller) than the input signal before the delay time. Based on the increase signal and the decrease signal, the latch outputs an increase-decrease signal indicating whether the input signal is increasing or decreasing. Based on the thermometer code signal and the increase-decrease signal, the generation circuit generates a pulse detection signal and a pileup detection signal.
