Abstract

PURPOSE:To improve the Schmitt characteristic, by making the impedance at the view from an input infinite. CONSTITUTION:A P channel transistor (P FET)34 is provided between a circuit point 32 and an output terminal O1 and an N channel transistor (N FET)35 is provided between a circuit point 33 and the output terminal O1, and gates of FETs 34 and 35 are connected commonly to an input IN. A P FET36 is provided between the circuit point 32 and a power source VDD, and an N FET37 is provided between the earth and the circuit point 33, and gates of FETs 36 and 37 are connected commonly to the input IN. Further, a P FET38 is provided between the circuit point 32 and the earth, and an N FET 39 is provided between the circuit point 33 and the power source VDD. The output terminal O1 is connected to an output out through inverters 40 and 41, and this output out is connected to gates of FETs 38 and 39. In this constitution, the impedance at the view from the input IN becomes infinite, and the Schmitt characteristic of this circuit is determined by the characteristic of internal elements.
