Abstract :
An analog CMOS four-quadrant multiplier and a two-quadrant divider circuit are introduced. The multiplier operates for a power supply ±1.5 V and its differential input range is ±1 V with less than 0.2% linearity error. The THD is less than 0.3% with input range up to ±0.8 V. The divider offers the facility of independent control of the sensitivity and has acceptable precision useful in analog signal processing, fuzzy control and instrumentation applications. Experimental results verify the simulation ones demonstrating the feasibility of both circuits
