support about electronic-circuitry application

[Alex]

Hello,
in terms of an practical exercise it is required to do a electric
circuitry consisting of an parallel-circuitry between one J-FET and one
non voltage dependent resistor. The first component (J-FET) ist
operatet (biassed) up to maximum pinch-off current (current drain = 0).
The resulting point of this pinch-off-state should be wired as the
drain-connection. This is not an big task, so your help would be very
appreciated as far as circuitry-design is concerned. An solution with
simulation software such as PSpice would be good for me as well.

Please give me a hint.

If the FET is off and the resistor is in parallel, then just model the
combination as the resistor alone. Sounds like a homework problem.

Yes, but I need some parameters of the complete construction. So I have
to use J-FET and resistor.

If your teacher is not able to explain the assignment well enough for you
to complete it, then you need a new teacher.

Good Luck!
