Q5) [10 Pts] Consider a circuit w/ two outputs f1 and f2 f1=m(1,5,7,9,13,15)f2=m(0,1,2,3,5,7,15) a) Optimize every function independent of the others. What is the cost (number of MOSFET transistors)? b) Optimize the circuit, globally, by exploiting the optimization opportunities across all functions. What is the cost (number of transistors used to realize the function as a CMOS circuit)? Q6) [10 Pts] Design a circuit that find the square ( X2) of a 2-bit value X(x1x0). Try to optimize the circuit as a whole (it is a multioutput circuit). Q7) [5 Pts] What is the functio QB) [5 Pts] Assign variables to the inputs of the AND-XOR circuit below so that its output is f(x,y,z,w)=m(6,7,12,13). What is the solution if the AND gates are changed to NAND gates? Show how to use a 2-input XOR gate to perform inversion
