Abstract

In this study gain flatness and accuracy of DC-stabilized non-inverting composite amplifiers are investigated. Experimental design has been introduced to improve gain flatness. The negative effect of DC-stabilization on the gain flatness of the operational amplifier has been eliminated by a simple resistor and capacitor. At the same time, the desired amplifier gain value can be adjusted by design. A high performance DA compositional amplifier design with high accuracy and ideal for gain flatness,high bandwidth  was achieved in this study..
