Please answer briefly and correctly.
The NMOS transistors shown in the figure have identical channel lengths and identical channel widths. They are biased by dc gate voltages \( V_{B 1} \) and \( V_{B 2} \), and conduct a dc current \( I=1 \mathrm{~mA} \) in saturation. While M1 operates with a source-bulk short, M2 doesn't. The drain-source saturation voltage of M1 happens to be \( 125 \mathrm{mV} \). Determine (a) the drain-source saturation voltage of \( \mathrm{M} 2 \), (b) overdrive voltage of \( \mathrm{M} 1 \), (c) overdrive voltage of M2, (d) sheet current of M1, (e) sheet current of M2, (f) aspect ratio of M1, and (g) aspect ratio of M2. Also derive by inspection the relationship between dc small-signal output resistance \( r_{o} \doteq v_{0} / i \) and dc small-signal device parameters.
