1535416 Multipliers SONY CORP 22 April 1976 [23 April 1975] 16375/76 Heading G4G [Also in Division H3] Two D.C. voltages E 1 , E 2 are multiplied by a circuit 30 to produce an output E 3 . A current mirror 33, 51 feeds a current to an emitter coupled pair 31, 32, the respective transistors 31, 32 acting as current sources for further emitter coupled pairs 34, 35 and 36, 37. Thus the collector current of, e.g., 31 is proportional to E 2 , and the collector current of 34 or 35 is consequently proportional to E 1 x E 2 . |
