Abstract

Op-amp is a device that is commonly used in an analog circuit that was designed to perform several of functions. Typically, as the CMOS technology becomes more advance, various of op-amp topologies are invented to suit the technology. However, most studies on past technologies have found out that the parameters are still not sufficient enough in order to meet the performance goal of CMOS 0.13μm technology. In order to select the right op-amp for CMOS 0.13μm technology, various performance specifications need to be taken into consideration. Therefore, in this project four types of op-amp topologies (Folded-Cascode, Telescopic, and Multi-stage) are characterized based on gain, output voltage and power consumption using CMOS 0.13μm technology. The development of this project consists of designing each topology by using Cadence Virtuoso tool. These op-amp topologies are compared to select the one that can provide the best performance in term of high gain, and low power.
