    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.
