ABSTRACT:
Integrated injection logic circuits and semiconductor devices employing threshold functions. Multiple-collector input transistors have their collectors connected to the bases of one or more output transistors. The output transistors have different weighted levels of injection current. The switching states of the output transistors are functions of the number of and conduction state of input transistors to which the output transistor are connected and to the weight of the injection current associated with the output transistor.
