Abstract
A static logic circuit utilizing transistors of the MOSFET type includes a high resistance load transistor, a low resistance logic network having a large self-loading capacitance, and a gating transistor connected in series between the network and the load device. The logic network controls the output voltage across a load capacitor by grounding the load transistor output for selected input data, and the gating transistor is biased to turn OFF when the voltage across the large self-loading capacitance exceeds a predetermined level, thereafter isolating the input network from the load capacitor and speeding up the output transition by decreasing the time required to charge the load capacitor.
