D Question 1 In the following circuit, Vdd is power, Vss is ground. What function is Vout? B U Vout= AND(A, B, C) Vout NAND (A, B, C). = Vout NOR(A, B, C) O Vout = OR (A, B, C) 2 pts = out Question 2 In this circuit, the power is on the top and ground at the bottom. What function is OUT? OUT (A+B'C')D OUT (A(B+C)+D)' OUT (A+B+C)D' O OUT=A(B+C)+D 3 pts OUT The following is a NOT gate implemented by an nMOS transistor and a resistor. The power is on the top and ground at the bottom. Compared with the NOT gate implemented by an nMOS and a pMOS, i.e., CMOS discussed in the class, what is the pro and con of this nMOS implementation? A pro: few transistors, con: more power consumption pro: few transistors, con: slower pro: avoid pMOS which is hard to make. con: the resistor takes too much area pro: faster, con: too big Question 4 What function Y(A, B) is implemented by the following circuit? The power symbol is the T-like end, and ground symbol at the bottom. Hint: Fill out the truth table. OY=A+B' OY-AXOR B O Y=A*B' OY=A'+B O Y = A*B 3 3 pts Y B Question 5 FL A O a NAND gate wrong B The triangle at the top is the power, and the symbol at the bottom is the ground. The circuit is an OR gate O a NOR gate B 2 pts
