Circuits and Systems
In Present scenario battery-powered hand-held multimedia systems become popular. The power consumption in these devices is a major concern these days for its long operational life. Although various techniques to reduce the power dissipation has been developed. The most adopted method is to lower the supply voltage. But lowering the V dd reduces the gate current much more rapidly than the sub-threshold current and degrades the SNM. This degraded SNM further limits the voltage scaling.
