Abstract
In a push-pull switching circuit, whose output transistors are controlled by complementary control signals, one of the gate electrodes which carries a 'low' signal is kept just at the threshold voltage of the output transistor to be cut off by means of a transistor substantially identical to the output transistors, the gate electrode and the drain electrode of this transistor being interconnected. The junction of this gate and this drain is connected to the common of two cross-coupled transistors, which are connected by their drains to the gate electrodes of the respective output transistors.
