Manni Chen 304145309 HW5 1.a, b c. C D is usually smaller than C E because we got C D by matching at the ½ VDD, but find CE by tracking the integration of current. When VDD increases, Both CD and CE increases slightly and the energy also increases. 2. a,b Logic 0 leakage Logic 1 leakage average W/o sleep transistor 221.5fJ 335.8fJ 278.65fJ head switch 42.3fJ 6.5fJ 24.4fJ foot switch 7.2fj 38.8fJ 23fJ both switches 5.38fJ 7.68fJ 6.53fJ From the chart, using both switches is the best solution for leakage energy reduction.
