Four quadrant multiplier core with lateral bipolar transistor in CMOS technology

A four quadrant multiplier core using lateral bipolar transistor in CMOS technology has been fabricated, tested and analysed. It has a high precision of linearity (with an error smaller than 2% for inputs over half of the power supply voltages), small offset of a few millivolts at the inputs, a small output offset of about 1.5 mV and a small dissipation.
