Abstract
A CMOS logic circuit including (a) a PMOS transistor, (b) an NMOS transistor, (c) a first coupling capacitor electrically connected only between a gate and a substrate of the PMOS transistor, and (d) a second coupling capacitor electrically connected between a gate and drain of the NMOS transistor, wherein the PMOS and NMOS transistors include substrate voltages which are made higher than associated reference voltages during rising edges of signals transmitted to the gates, and made lower than the associated reference voltages during falling edges of the signals. The gates of the PMOS and NMOS transistors are electrically connected to each other, drains of the PMOS and NMOS transistors are electrically connected to each other, and an input signal is introduced into the electrically connected gates, and an output signal is taken through the electrically connected drains.
