2. Suppose you are in a two-period world where there is only the present and the future. You are currently an economics major in college. According to a recent study, you will earn about $98,000 in the future. But as a college student working part time at McDonald's, you are only pulling in $15,000 today. You also have bequests from your parents, which are assets worth $10,000. Suppose that the real interest rate is 5 percent, $\beta$ = 1, and utility is logarithmic. (a) What is the net present value of your human and total wealth (that is, $\tilde{X}$)? 2 (b) What is your consumption today? In the future? (c) What happens to your consumption if, rather than making $98,000, you make $102,000 in the future? (d) Suppose the discount factor is less than one, $\beta$ < 1, and the interest rate is zero, $R$ = 0. How would this change your answer?

For the questions below, assume the following device parameters: k'n=µnCox=200 µA/V², ?'p=µpCox=80 µA/V², |VLIN | = infinite Vto,N=Vto,P=0.5V, PHI=|2?F|=0.85V for N and P, ?=0.3 V^0.5, ?=0.1 V^-1 1) Current Mirror: a. The simple mirror in Fig. 1(a) is designed with W/L to have gm=0.25mA/V at 20 µA for the input leg of the mirror with W/L ratio on the output leg 6X larger. If Iref = 20 ??, calculate the output current for Vout = 0.5, 1.0, and 2.0V. b. The mirror is updated to be a standard cascode current mirror in Fig. 1(b), using the same W/L ratios as above for the input leg and output leg. If Iref = 20 µA, calculate the output current for Vout = 0.5, 1.0, 2.0V. c. Calculate the output resistance of these two circuits. Using this resistance, estimate how much the current should change for a 1V change in output voltage change. How does this compare to your answers in (a) and (b)?
