Two useful low voltage multipliers are presented in this paper. They employ only two transistors between the rails and perform four-quadrant multiplication. These circuits are based on the V/sub gs//sup 2/ technique, and use MOS transistors in saturation in order to achieve squaring of the differential inputs. Theoretical results are verified with HSPICE simulations using a 3.3 V, 0.35 /spl mu/m CMOS process.
