Abstract: The circuits include a complementary inverter, comprised of first and second transistors responsive to an input signal, and means responsive to the input signal, for placing the conduction paths of additional transistors in parallel with the conduction path of the first or the second transistor. The conductivity of the additional transistors is controlled by a feedback signal derived from the output of the inverter. When an inverter transistor is turned on the additional transistors connected across it are also turned on causing the equivalent impedance of the ''''ON'''' portion of the circuit to be much lower than the ''''ON'''' impedance of either one of the inverter transistors.
