It should be *obvious* from the circuit!

It's not, at least not to those among us, such as myself, who are not
so clever.

My circuit is as simple as it gets. Hve the cathode of the CF at
+50v, and have a 1M R to drain 0.05mA through the diode. Much more
current could be used.

This method means that detection of weak signal lower than the
forward voltage of the Ge diode of 0.27v peak approx are not
subject to the non linear turn on of the diode, ie, there is no
clipping by the diode.

Is what you are saying is that the diode in your circuit is always
"turned on"?

Snip

Congratulations for the continuation of one of the most retarded
threads I've yet read. Never heard of biasing a diode or being unable
to understand doing so is pretty pathetic. Electronics does not get any
simpler than this.

Why don't you cross post this to more news groups so more people can
have a laugh.
