Abstract

1351685 Voltage dividing apparatus R C A CORPORATION 22 July 1971 [24 July 1970] 34363/71 Heading G3X A voltage divider network produces an output which is a regulated proportion of an input voltage independent of temperature effects at semiconductor junctions. The magnitude of the output, and its stability, depend only on the ratios of resistors in the network. In the circuit shown in Fig.3, which is capable of producing at terminal 26 a voltage V o greater than one-half of the supply voltage V s , a transistor 70 is arranged in common-emitter configuration together with a transistor 72 operated in commoncollector mode. The circuit is formed on a monolithic semi-conductor chip and also includes resistors 74, 76, 78, 80. It is shown that the output at terminal 26 is stable against variations in the base-emitter characteristic voltage of the transistors if resistors 74, 76 are of equal value. The magnitude of the output then depends solely on the relative values of resistors 78, 80. Similar circuits including additional transistors or diodes are described, enabling smaller propertions of the input voltage to be obtained, Figs. 1, 2, 4 (not shown).
