Abstract

A logic circuit comprising a phase divider circuit, a transistor receiving an inverted output from the phase divider circuit, and an active pull-down circuit coupled with an output terminal in connection with the transistor and adapted to be operated by a noninverted output from the phase divider circuit, in which the phase divider circuit is provided with a variable impedance circuit, which is coupled with the inverted output and of which the impedance is adapted to be varied according to the input signal.
