Abstract
Two analog-circuit-building blocks, called the three-input amplifier and the complementary three-input amplifier, are described. The three-input amplifier may be configured directly to have a gain of one-half, and may also be used as a voltage summer. The complementary three-input amplifier may be configured directly to have gain of two or a negative gain. The three-input amplifier is useful in the area of D/A conversion, while the complementary three-input amplifier is suited to a role in A/D conversion. Three versions of the three-input amplifier and its complement are fabricated. Experimental results confirm the characteristics of the amplifiers as predicted by theoretical analysis
