Abstract
1,136,004. Transistor amplifier circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 20 May, 1966 [24 May, 1965], No. 22574/66. Heading H3T. A circuit for generating floating output voltage (i.e. not related to earth) proportional to an input voltage, comprises a resistance 25 supplied with current from constant current generators 14 and 24 and from variable current generators 13 and 23 controlled by the input. With zero input all four generators supply equal currents and no current flows through resistance 25. An input applied to terminal C causes a differential variation in the currents supplied by generators 13 and 23 thereby causing flow through the resistance 25 of a current proportional to the input and of a sign corresponding to the sign of the input. The resistances in corresponding transistor circuits are nominally equal but may be adjusted to compensate for variations in the transistors. The pairs of transistors 13 and 23, 14 and 24 may be located in the same box so that each transistor of a pair is at the same temperature.
