Q3. a) A CMOS inverter is built in a process where k' = 100A/V, k'p = 42A/V, Vin = 0.7V, Vip = - 0.8V,and VDD = 3.3V. Find the switching thershold voltage Varif (W/L)n = 10 and (W/L)p=14. [4] b) Find the values of , and 3, needed to obtain an inverter thershold voltage VM of 1.3V with Vpp = 3V. Assume that Vm = 0.6V, V = -0.82V. What would be the relative device sizes if k' = 100A/V and the mobility values are related by un = 2.2 p? [6]
