Good FET Probe Circuit Diagram?

Short answer is "north"! All the good fet probe circuits are in the north.

Try to be less descriptive of your requirements. I'm overwhelmed by all the details.

Good? Probe What? Bandwidth? IF by single rail, you mean single power supply, you're gonna have to jump thru hoops if you expect to measure bipolar signals. Unless your requirements are very restricted, and so far we can't know that, you'll be far better off to bite the bullet and use bipolar supplies. mike

Thanks Philip

I know someone with copies of Elektor, I'll take a look.

It's online. You can get to it by searching the Elektor site, but I'll save you the trouble:

Hi Wayne,

I've not built it but Elektor Electronics did publish a construction project for one , perhaps if you build it you could post if it is any good!
