| Plot the measured voltage amplitude seen at the source. The nominal source current in M<sub>1</sub> is (Vn - V<sub>GS</sub>) / 4.7KΩ or 720uA. We can calculate r<sub>s</sub>from this current as ohms. How does this r<sub>s</sub> compare to the from the test data? Change the value of R<sub>1</sub> from 4.7 KΩ to 2.2 KΩ and re-measure the output impedance of the circuit. How has it changed and why? | Plot the measured voltage amplitude seen at the source.
