Design and Implementation of Optimized Parameter Based Operational Amplifier for High Speed Analog Signal Processing

The most domineering device in the field of electronics is the Operational Amplifier owing to its widespread appliances via analog computation and signal processing. The major objective of this paper is to design and implement a two stage complementary metal-oxide-semiconductor operational amplifier through precise specifications and also investigate the different outcomes concerning several parameters as well as process variations. The two-stage complementary metal-oxide semiconductor Operational Amplifier operates under ±1.8V supply voltage and the simulation is performed through Tanner EDA. The important consideration throughout design of this Operational Amplifier circuit is its feasibility concerning the environment and appliance. Moreover, the feasibility of this circuit vastly depends upon the process variation, which brings about a significant impact over analog circuits in terms of quantifiable and foreseeable deviation of the output.
