Abstract

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