Abstract

A four-quadrant multiplying device comprising a differential amplifier composed of two transistors that are connected as a second differential pair and on whose bases the difference voltage produced in the input elements of the differential amplifier is applied, and whose collectors are coupled with cross-coupling to the collectors of the transistors of the first differential pair, with a first input signal supplied in the form of difference current to the input elements, while a second input line is supplied in the form of current difference to the common electrodes of the pairs first and second differentials, characterized in that the difference voltage produced in the input elements is applied to the second differential pair by means of a second follower circuit having an adjustable direct current set point.
