Abstract

The problems involved in the design of a transistor operational amplifier suitable for a repetitive computer are discussed. An analysis of parallel feedback applied to an active quadripole is advanced to show that the maximum computing accuracy for a given number of transistors is obtained by employing cascaded, common-emitter stages without local feedback. The factors which determine the bandwidth of a repetitive computer amplifier are discussed and the associated stability problems are solved by appropriate shaping of the loop transmission of the amplifier.
