The power consumed in a device is composed of two types – dynamic, sometimes called switching power, and static, sometimes called leakage power. In geometries smaller than 90nm, leakage power has become the dominant consumer of power whereas for larger geometries, switching is the larger contributor. Power reduction strategies can be used to minimize both read more.
