Abstract

1516125 Transistor stabilizing networks NATIONAL SEMICONDUCTOR CORP 28 July 1975 [6 Nov 1974] 31469/75 Heading H3T An electric circuit comprises a plurality of pairs of transistors with their base-emitter junctions connected serially in a loop the algebraic sum of the base emitter voltages being developed across one or more non-zero resistances in the loop. The transistors of each pair carry the same current and the base emitter voltages of the transistors of each pair opposing one another around the loop. If terminals 16 and 24 in Fig. 1 are connected together a loop 16-28-12-30-18-10-26-20-32-24-16 is formed through the base-emitter junctions of the transistors. The algebraic sum of the base-emitter voltages, which is fixed by choice of the emitter areas, appear across the resistors. Since the series connected transistors 10, 12 have their base-emitter junctions connected in opposition round the loop, as do transistors 18, 20, changes in the collector currents do not affect the algebraic sum of the baseemitter voltages. A further transistor may be provided with its emitter collector path in series with transistor 10 and its base connected terminal 22. To provide a regulated current, resistors 26, 28, 30 are made zero and a voltage is applied through a resistor to terminal 14, the regulated current appearing at terminal 22. A regulated voltage may be obtained across terminals 22, 24 by making resistors 26, 30 and 32 zero and connecting terminals 14, 16 through a resistor to a current source.
