Abstract

Operational Amplifiers (Op-Amp) are one of the most widely used building blocks for analog and mixed-signal systems. They are employed from dc bias applications to high speed amplifiers and filters. Different architectures like Two-Stage Op-Amp and Folded Cascode Op-Amp are simulated with different characteristics like slew rate, offset voltage, gain. For improving the slew rate, few modifications are carried out by adding current replication branch and auxiliary circuits in Op-Amp.
