Coignof vantage of Transistor Stack and Input Vector Control Method in Leakage Current Reduction

Leakage current has become a regime in deep sub micrometer circuits.When we move from one technology generation to another technology generation leakage current component is increasing.Out of the total power dissipation majority is the leakage power.The dominant component of leakage power is sub threshold leakage current.Minimizing leakage current is very important in battery powered applications since the leakage drains the battery when circuit is idle.In this paper a survey is done in such a manner so as to outline what so far has done to reduce the leakage power.The paper is organized in such manner that it gives a brief description about standby leakage mechanisms, various standby leakage reduction techniques and what all are the existing technique's available.
