  • Patent number: 4247789
    Abstract: An electronic circuit adapted to multiply/divide analog input signals, such circuit having a first set of four transistors with serially coupled base-emitter junctions arranged to produce an output current in the collector electrode of one of such transistors which is proportional to the product of currents fed into the collector electrodes of a second and third ones of the four transistors divided by current fed into the collector electrode of a fourth one of the transistors. The circuit includes a second set of four transistors, each one having a base electrode and an emitter electrode connected to the base electrode and emitter electrode, respectively, of a corresponding one of the first set of transistors to produce a current in the collector electrode thereof related to the current flow through the ohmic emitter resistance of the corresponding one of the transistors in the first set coupled thereto.
