Abstract

PURPOSE:To increase the noise margin of an input signal, by using a static type comparator as an input circuit and applying an input signal to one input terminal and a reference voltage generated in an integrated circuit to another input terminal. CONSTITUTION:When an input signal is at ''1'' level, the source of an MOSFETT1 is at Vc potential, and an MOSFETT4 turns on and a T3 turns off. When the input signal changes from ''1'' to ''0'' level, the FETT4 turns off and the T3 turns on through the difference of conductive resistance of the MOSFETs T1, T2, and the output optential is at ''1'' level. Inversely, when the input signal changes from ''0'' to ''1'' level, the FETT3 inverts off and the T4 inverts on through the difference of conductor resistance of the FETs T1, T2 and the output potential is at ''0'' level. Specified noise margin can be obtained by the hysteresis characteristics of a comparator 10.
