all nMOS transistors have small signal parameters, gm,n and Ton, and all pMOS transistors have small signal parameters, gm.p and ro.p. Assume that gm,xfo,x >> 1 for x = n, p. (a) Calculate Rout. (b) Calculate Vout/Vin. (c) Calculate the range of values for Vout such that all transistors remain in saturation. Assume that all nMOS transistors have the same overdrive, Vod,n = VGS,n - VTH,n, all pMOS transistors have the same overdrive, Vod,p = VSG.p - VTH.pl, and the supply is VDD.
