Abstract

A logic circuit comprises an input terminal receiving an input signal of input pulses; first and second stages of C-MOS circuit formed by a first MOS FET of one channel type formed in said semiconductor substrate of one conductivity type and a second MOS FET of other channel type formed in well region of other conductivity type formed in the semiconductor substrate, said first and second stages being connected in a cascade connection; a first power terminal applying a first power voltage to the semiconductor substrate; a second power terminal applying a second power voltage to the well region; and a pulse converter converting the input signal to a pulse signal having a reference voltage of the second power voltage and short width pulses of the first power voltage produced in synchronism with the input pulses.
