Consider a CMOS inverter utilizing the devices with parameters for NMOS: μnCox = 250 × 10−6 A/V2, VTN = 0.8 V, λN = 0.01, (W/L)n = 5 μm/ 500 nm μpCox = 120 × 10−6 V/A2, VTP = −0.9 V⋅ λP = 0.015, (W/L)p = 5.5 μm/500 nm, VDD = 5 V. a. Find the VM value for the inverter. Include the channel length modulation effect. You can use MATLAB or a similar tool to solve the equation, but show how you build the equation. b. Keeping the NMOS size constant, find the proper size that results in tPHL = tPLH.
