Construct the CMOS logic circuit that implements Y = a +a+b+cb using the fewest possible transistors. You are allowed to use inverted inputs (e.g., a) rather than adding inverters to create these signals. A CMOS metal layer with resistivity, p, 3x1062-cm is 0.6m thick. It is used to draw a signal trace that is 100m long and 0.75m wide. a) Calculate the sheet resistance, Rs, of this metal layer. b) How many "squares", n, are in the signal trace? c) Use the results in (a) and (b) to determine the resistance of the trace.
