This paper presents the detailed design of a single stage telescopic op-amp and single ended folded cascade op-amp by using design equations. The concept of telescopic & folded cascode op-amp topology, its design methodology in terms of procedure, criteria and equations has been presented. The performance characterizing parameter & operations of their proposed structure are discussed in fundamental form. The proposed telescopic structure yields medium gain while the folded cascode provides comparatively high gain than the telescopic op-amp.
