[ARC5] ARC-2: IF Regeneration is a "No"

Decreasing the input and output DC blocking capacitors does - I 
think- increase the filter impedance but a higher filter 
impedance with the same value 5pF coupling capacitor means more 
coupling and larger bandwidth.
----------------

Ahhh!  That makes sense.
Gives me more ideas.  Thanks!

You might consider making a simple solid state negative impedance 
generator to introduce resistive regeneration. This way the 
filter tuning should remain unaffected.

I've no knowledge of this concept.  I looked it up in
Wiki but I'm not "connecting the dots."
Can you please give details of how this could be
implemented in the IF circuit?
Thanks, Dave S.
