Class Information
Number: 341/134
Name: Coded data generation or conversion > Analog to or from digital conversion > With particular solid state devices (e.g., gunn effect device, josephson device, drift transistor, using solid state active devices as impedances) with other at longer intervals) > Integrated injection logic
Description: 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.
