Uh ? There's several big errors in his post !

Nope. Just in your reading of it. The OP has INVERTED the
transistor, emitter now has function of collector and vice versa.

He only erred in terminology, calling it "common collector".

How bizarre !

Does *any* current flow that way ? I.e. collector -ve wrt emitter for an npn
device ?

Graham

Duh! It's NPN viewed from both directions ;-)

...Jim Thompson

In the days of MAT100s I could see that working but it somewhat surprised me to
see it work with a modern device.

I can't see the point of doing it though !
