Abstract
A three-valued signal generation device includes a first differential amplifier that outputs a differential signal, a second differential amplifier that outputs a differential signal and an inverted differential signal in accordance with a level based on a reference voltage of an inverted pseudo LFPS signal, which is obtained by inverting a logic level of the pseudo LFPS signal, a first signal synthesis unit that synthesizes the differential signal from the first differential amplifier and the inverted differential signal from the second differential amplifier to perform positive logic output of a three-valued LFPS signal, and a second signal synthesis unit that synthesizes the inverted differential signal from the first differential amplifier and the differential signal from the second differential amplifier to perform negative logic output of the three-valued LFPS signal.
