Using the CMOS long-channel process (1 µm), estimate the AC and DC drain currents in the
circuit seen in the figure below. What are $V_{gs1}$ and $V_{gs2}$? What happens to the DC biasing if
we replace the capacitor with a short? What happens, with the capacitor in place, to the DC
biasing if we short the big resistor (show that the DC biasing isn't affected; however, the
amount of AC current supplied by $V_{in}$ goes up). How do the currents in M2 change if we
double its width (put two 10/2 transistors in parallel)?
