Abstract
A Schmitt trigger circuit includes a first circuit; a second circuit; a first switch; a third circuit; and a second switch. The first circuit output the output signal of a second or first logical level. The second circuit is coupled to a first potential node at a first end, and sends a current between the first end and a second end based on the output signal. The first switch electrically couples or uncouples the second end and a first node based on a selection signal. The third circuit is coupled to a second potential node at a third end, and sends a current exclusively with the second circuit between the third end and a fourth end based on the output signal. The second switch electrically couples or uncouples the fourth end and the first node based on the selection signal.
