1. Consider CMOS inverter with (W/L)n = 20, (W/L)p = 40, u.Cox = 2u.Cox = 20 UA/V2 In addition, assume that if Von = IV pl = 0.7V and Vpp = 3.3 V Calculate the inverter threshold voltage, VM 2. A CMOS inverter utilizes Vpp = 3.3 V, Vto = \VTpl = 0.7 V, and un = 3up = 480 cm?/Vs. Find the ratio of (W/L), to (W/L)p so that the switching threshold voltage, Vm= 1.5 V. 3. (a) Consider CMOS inverter with (W/L)n = 20, (W/L)p= 40, u.Cox = 2u, Cox=20 UA/VP Assuming that Vin = VIPI = 1 V and Vpp = 5 V, find the peak current drawn from Vpp during switching. (b) Consider CMOS inverter with (W/L)n = 40, (W/L)p = 40, u,Cox = 2uCox= 20 UA/V2. Assuming that Vin= \VTP) = 1 V and Vpp = 5 V, find the peak current drawn from Vpp during switching. 4. For a particular inverter design using a power supply of 1.5 V, VOL = 0.1 V, Von = 1.4 V, VIL = 0.4 V and Vin = 1.2 V. What are the noise margins? What is the width of the transition region?
