Please use the 180 nm process parameters shown at the end of homework for all the homework questions. For NMOS as Rn = 6.47 KΩ, for PMOS as Rp = 29.6 KΩ, and C1 = 0.89 fF)Design the static complementary gates (CMOS gates) for the following logic expressions using pull-up/pull-down networks. Use a truth table to show logical equivalence for converted expressions. Assume inverted variables are available, i. e., you do not have to add inverters for complementary variables.
