That means the leakage power is less when the Vt is high and when Vt is low the leakage power is less so according to ur statement it is inversely proportional am i right?
hi vlsi
on time Delay of any transistor depends on the threshold level,,if th is more then it takes more time to turn on so the delay of that cell becomes more,,, on the other hand to get more Vth need to dope the substrate heavily which decreases the minarity careers by which the leakage power comes down,,,,,,
SO HVT CELLS GIVES LOWPOWER AND LOW PERFORMANCE
