Hi all!
I need a schematic for mosfet buffer with BS170 or J201 or similar. To have the input of resistance 1Mohm. Power supply it with Ucc=+/-9V.
thank you!

The J201 is an N-channel jfet.

Are you trying to buffer the output of a MOSFET or use a MOSFET to make a buffer?
Probably use a MOSFET to make a buffer.

Need more information. How much current? Will a voltage follower do the job? Is this a High/Low switching output or analog?

Tel me more.
