Optimization of Power and Gain in Two-Stage Op-Amp by Using Taguchis Approach (original) (raw)

Advanced Materials Research, 2013

Abstract

This paper presents a method based on statistical approach which known as Taguchi method. This method is used to optimize power dissipations and gain in a two-stage op-amp. Standard L27 which uses three factors and two outputs is chosen to optimize power and gain in the circuit. Simulation of the circuit has been implemented by using Mentor Graphics DA-IC. From the simulation, the results showed that total power dissipation has decreased from 3.9643 mW to 1.0345 mW. The percentage of power reduction is 73.9%. The overall gain also has been improved from 22 dB to 45.49 dB. The percentage of increment gain in two-stage op-amp is 56%.
