Design of ACP Resistor-Coupled Switching Circuits

Directly coupled logic circuits utilizing silicon transistors have been developed in the Advanced Circuit Program. Silicon transistors possess sufficient field gradient in the collector-base “diode” to permit high-speed operation under a forward-biased condition. Current-switching techniques provide the well-controlled voltage levels which permit operation in this region without sacrificing high speed. Operation in this region permits circuit simplification and low power dissipation.
