ABSTRACT:
A logic gate using a single transistor having two emitters interconnected by a resistor which is center-tapped to the transistor base. The collector is connected through a load resistor to the DC supply rail.
A logic gate using a pair of IGFETS having sources connected together, the drains connected through a common resistor to a DC supply rail. The gates are connected through diodes to the common sources of the channels.
Various logic gate functions, including EXCLUSIVE-OR and EXCLUSIVE-NOR functions based on these gates.
