Abstract
Digital integrated C-MOS circuit in which two cross-coupled P-MOS transistors are connected by two separation transistors (N-MOS) to two complementary switching N-MOS transistor logic networks. The gate electrodes of the separation transistor are connected to a reference voltage source. The switching speed of the C-MOS circuit is increased in that (a) the voltage sweep across the logic networks is reduced; (b) each P-MOS transistor, which is connected by a separation transistor to a junction of the logic network to be charged, is slightly conducting and so is 'ready' to charge such junction, and (c) the separation transistor between the fully conducting P-MOS transistor and the junction to be discharged in the second logic network constitutes a high impedance which prevents the conducting P-MOS transistor from charging that junction.
