摘要：In this paper we have presented a method for designing an Operational Amplifier using Differential
Amplifier and Common Source Amplifier (CMOS-Two stage Op-Amp) using Cadence Virtuoso 180nm Technology.
An Operational Amplifier is a DC- coupled High -gain electronic voltage Amplifier with a differential Input and
usually a Single-ended output. Op-Amps are one of the widely used electronic devices at the present time, being used
in a wide range of industries, consumers and scientific devices. Op-Amps are mainly used as a voltage follower, active
rectifier, current to voltage converter, Mathematical operations and in different types of voltage filter. Here we are
discussing about different operational parameters of Op-Amp such as Gain Band width, Gain, Phase Margin, Power
dissipation etc. We are Designing the Op-Amp circuit with specifications and completing the design flow and verifying
the DC analysis, AC analysis and Transient analysis.
