In most operational amplifiers, speed and accuracy are basically determined by the settling behavior in timedomain. High speed calls for a single pole response and a large unity gain frequency. In this paper a folded cascodeoperational amplifier of general purpose is presented. The results presented are obtained through schematic level simulationusing the pyxis schematic in mentor graphics tool and a standard 130nm technology process. The results obtained includeopen-loop gain of 58 dB, the Gain Bandwidth product of 2.5GHz. Without additional components, the high frequencyresponse of the classical folded cascode operational amplifier is improved.
