Book excerpt: This research examines a unified approach to several of the problems associated with Operational Amplifiers (OAs), namely, speed, accuracy, and frequency dependent gain. The approach which is examined is the Composite Operational Amplifier(CNOA), where N=2, 3, or 4 single OAs. The CNOA is found to greatly extend the useful operating frequencies of the OA while maintaining low sensitivity to circuit element variations and a high degree of stability. It also provides a method for obtaining a fast and accurate OA. An additional feature of the CNOA is that can be implemented using current technology. A computer model for the single OA was created and validated, and provided the basis for proving the superiority of the CNOA. Theoretical and experimental results were used with these computer simulation results to fully substantiate the findings. (Theses) (Author).
