Hi everyone! Attached is the Mosfet diagram and also my attempted answer in constructing the t-equivalent circuit. I would like to know whether my circuit is correct...I was wondering whether R0 was actually Rl so i think this could be a mistake on my drawing. Also, do i need to have capacitors because dc has been grounded...ok i dont think i needed to draw in the capacitors...

I would also like to ask a question on working out the gain...one question at a time though!! Thanks XD

 

Replace all capacitor by a short circuit.
And as for T-model look here on page 6.

Thanks for the reply. I noticed this page prior to posting however. My problem with the website is that it does not tell you how to take a circuit, like my first attachment, and change it to the T-model.

 

Notice tha D, G and S pins on the T-model. These correspond directly to the JFET pins. Substitute the JFET with its subcircuit - the T-model.
Since you now work on the small signal realm don't forget to short-circuit all the large capacitors. The resistors of the circuit stay as they are.

 

oki doki, so for my attachment, all i need to do is short circuit the capacitors and everything else is fine?
