DEFINITION

Classification: 341/134

Integrated injection logic:

(under subclass 133) Subject matter having a complementary transistor pair merged on the same substrate as an integrated circuit device, incorporating a vertical, inverse mode NPN (PNP) transistor, which can have isolated multicollector regions, and a PNP (NPN) lateral transistor, which serves as a current injector to inject charge current directly into the NPN (PNP) transistor base.
