Draw the small-signal circuit using the low-frequency T-model for the MOSFET calculate gm and 1/gm. Replace the coupling and bypass capacitors and estimate the low-frequency 3dB frequency using the short-circuit time-constant method (ignore r0 for these calculations but don't forget to put the source resistor back! And don't forget to include the 200 Ohm and 1/gm resistor in the calculation of R Cs).
