Digitally Programmable Composite Operational Amplifier Applications

Abstract

In this study, CMOS implementation of composite operational amplifiers onto a single chip is examined. Composite operational amplifiers are realized by interconnecting two or more single operational amplifiers in any one of four high performance circuit topologies. These high performance topologies result in composite operational amplifiers having useful bandwidths that are significantly larger than those associated with their constituent operational amplifiers without sacrificing closed loop gain. Computer simulations using PSPICE are compared with experimental results for performance evaluation. As an application a multiple feedback bandpass filter implementation is examined. This work successfully demonstrates that composite topologies can satisfactorily implemented onto a single chip. CMOS Composite Op Amps.
