Abstract

A four quadrant analogue multiplier that operates with a 1.4 V single supply and 0.6 V peak-peak input signals on both inputs is presented. It is based on a new low-voltage class AB differential amplifier with quiescent current control. Current efficiency and random distortion are introduced as quality factors to evaluate the performance of the analog multiplier. The multiplier presented here is characterized by a high current efficiency (50%), high bandwidth (40 MHz) and a high linearity (<1% distortion). Experimental results of a test chip are shown that verify low-voltage, low distortion and wide swing operation. Post layout simulations are presented that verify its wide bandwidth characteristics
