An important parameter in a CMOS inverter design is the ratioof KP to KN.

a. Investigate the effect of varying this ratio on thetransfer characteristics of the CMOS inverter in Fonstad, by sketching the characteristics forKN=50uA/V2 with KP = 50, 100, 250and 500uA/V2. In your sketch do accurate plots inregions I, II, and IV as shown in Fonstad. VDD=5V,VTN=1V, VTP=-1V.

b. From your results suggest an optimumKP/KN for the best noise margin.
