Description: This paper illustrates an approach to design a 4 Quadrant multiplier circuit using BJT. A Quadrant multiplier basically consist of 2 matched differential pair units with BJTs. This principle was established by B.Gilbert in 1968 and the circuit is known as Gilbert’s cell. The operation of BJT and its working as a differential amplifier is explained in brief. Referring to the operation of the differential amplifier as a two quadrant multiplier, the operation of a four quadrant multiplier was analyzed. The basic Gilbert’s cell was simulated using PSpice and improvements were made to increase it linearity of the basic circuit.-This paper illustrates an approach to design a 4 Quadrant multiplier circuit using BJT.
