Abstract

The title for this project is about optimization of power and gain in MOSFET multistage operational amplifier using Taguchi’s approach. Operational amplifier (op-amp) has a high gain value and widely used in all types of electronic gadget nowadays. It is a fundamental building block for many electronic analog circuits. Although the op –amp itself composed of various types of MOSFETs, it is usually considered as one of the ideal circuit. Designing high-performance analog circuits is becoming increasingly challenging with the insistent trend toward reduced supply voltages. The sophisticated of today's CMOS technology resulted in the various design of op-amp circuits to obtain optimum power and gain. By down scaling the size of the MOSFET channel length (L), the transition frequency increases (more speed) and at the same time the gain and power are optimized. Therefore, the Multi-stage op-amp was tested with different CMOS technologies of 0.13μm and 0.18μm with Cadence software to compare the performances in terms of power and gain. The best performances will be applied in Taguchi method to get the actual value of power and gain. From the simulation, the results shown both power and gain are increase from the original value.
