Is there a VHF AC model for a BJT collector feedback bias circuit

[Kevin]

Hi,
I know what the AC model for a CE amp looks like using the R1//R2 voltage
divider etc..
But what does the AC model for a similar CE amp using collector feedback
bias look like?

Cheers,
Kevin.

It looks like any other schematic with resistors, capacitors, and
current controlled current sources- what do you think it looks like...

Hi Fred,
Your very smart arn't you?
They must have let you out for the day!

How hard is it to AC_GND all DC sources, maintain all discrete component
connections to e-b-c terminals, and then substitute hybrid-pi components
for the transistor?
