Abstract: 1,176,876. Transistor switching circuits. INTERNATIONAL BUSINESS MACHINES CORP. 30 March, 1967 [24 May, 1966], No. 14459/67. Heading H3T. A switching circuit comprises a first transistor 12 with its emitter coupled to the collector of a second transistor 14, an impedance 32 for establishing a potential at the base of the transistor 14, and control means 34 coupled between the base and collector of transistor 14 to reduce the forward bias on the base-collector junction of transistor 14 when transistor 12 is cut off. Application of a negative potential -e 2 to the base of transistor 12 cuts it off, and switches on transistor 34 to hold the point 36 more positive than -e 2 .
