The purpose of the research was to analyse details in the application of operational amplifiers in precision analog circuits.Special attention was given to deviations caused by common mode rejection ratio, not thoroughly analysed in the literature.The research is started with theoretical analysis.Composite amplifier circuits are proposed to achieve better performances than with a single operational amplifier could be achieved.Benefits of the proposed circuits are shown by simulations based on the simulation models and measurements on the real model.The theory and practice introduced below could be well included in undergraduate course in analog electronics.
