A high speed analogue multiplier with a linearity of better than ± 1/3%

THE APPLICATION of transistor circuits to computers has been primarily in the digital field. The purpose of this paper is to indicate that they may also be applied to the simulation of analogue functions. The example, which is illustrated, is a four-quadrant multiplier, where the particular characteristics of semi-conductor devices facilitate the design. The following paper discusses the operations involved in multiplication and the particular circuits that perform these operations.
