Problem 1(d) PMOS Leakage Current VS V ds at 27°C and 100°C I ON /I OFF Calculation: 116.1 A / 95.35 A = 1.218 (for PMOS) μ μ Comparing leakage Current of PMOS and NMOS at 100°C: The ratio is: I PMOS /I NMOS = 95.35 A / 13.21pA 7218000 μ The leakage current of PMOS is very large compare to that of NMOS, that NMOS leakage current can even be seen as a negligible value.

By doing derivative of the curve, there are two points that slope = -1: (778.5mV, 1.668V) and (1.023V, 99mV) V OHU = 1.668V V OLU = 99mV V IH = 1.023V
