In Reply to: RE: Sorry - can't quite see how to plot the Drain current ... posted by andyr on August 19, 2024 at 17:05:06:
I don't know LTSpice but circuit simulators usually allow you to plot the current into the pins of components (you might have to explicitly save those pins before you run the simulation). Failing that, plotting the voltage across R4 and dividing by 10 gives you the total FET current.
From your answer to Tomservo, the plot you show looks nicely sinusoidal so there is no obvious clipping or large asymmetry. If that plot is the voltage across R1 you have a signal swing of ~ 200mVpp but your input source is 500mVpp so there is attenuation not gain.
