Design of a Low Power Two Stage Operational Amplifier using MT-CMOS Technology: A New Approach

Abstract: The birth of �Moore�s Law� provided a great insight to electronic industry. As a result of which so many technologies are adapted to increase the number of components on integrated circuits. One of which is Scaling .As scaling of technology is adapted, performance and efficiency of devices is improved to a great extent. But on the other hand power dissipation has become a matter of great concern. And it becomes the main constrain when it comes to portability of any electronic device. The operational amplifiers need no introduction as this device has become an integral part of fields like instrumentation, automotive and so on. So, this paper is proposing a design of a low power operational amplifier using MT-CMOS Technology. Various technologies for low power dissipation are also considered in this paper along with their advantages and disadvantages.
