摘要：This paper presents a novel methodology of simulation and realization of a various Op-amp topologies,such as two-stage, telescopic and folded cascade are discussed in this paper. The aim of the present workis the development of a tool box which contains the Matlab code to allow automated synthesis of Analogcircuits. This tool box is used to find the transistor dimensions (i.e.., width and length) in order to obtainthe performance specifications of a two stage op-amp, telescopic op-amp and folded cascode op-amp. InThis paper five parameters are considered such as Gain (G), Unity gain frequency (UGF), Phase margin(PM), Slew rate (SR) and Power consumption(P). The designs have been simulated by using 0.18μmCMOS technology with a supply voltage of ±1.8v.Finally, a good agreement is observed between theMatlab based tool box and electrical simulation.
