Abstract :
A simple 4-quadrant analogue multiplier based on the exponential terminal behavior of a silicon junction is described. The use of matched high gain transistors in the proposed temperature-compensate configuration simplifies the addition of logarithms and extraction of the antilogarithm. Experiments show that an accuracy of within 5% is easily obtainable.
