The scaling of nanometer technology has had a major impact on the power dissipation of CMOS circuits. As transistor size decreases it has become apparent that leakage power is becoming a dominant fighting force against future technology. In this paper the importance of static power consumption on the design of new and advanced CMOS technology is explored with the investigation of leakage power ...

Due to severe itching especially at night and the consequent loss of sleep there might be definite impairment in the efficiency of the labour or the fighting forces. The loss of man power may at times thus be considerable. In times of emergency, due to lack of proper care and attendance the death rate from its complications, e.g. nephritis, may also be high. Besides it is a very distressing con...

We show how the likelihood of conf...
