Abstract
A pulse generator circuit that outputs pulses having a predetermined shape from an output terminal based on a start signal includes a timing generator circuit that generates (n) signals (n is an integer greater than or equal to 2), a pulse width signal generator circuit that generates a first pulse width signal and a second pulse width signal a first filter circuit limiting the band of the first pulse width signal, a second filter circuit limiting the band of the second pulse width signal, first and second power supplies, a first variable impedance circuit controlled by the first filter circuit, a second variable impedance circuit controlled by the second filter circuit, and a switching circuit that alternately connects the output terminal to the first power supply using a logic function value based on at least part of the n signals.
