[sdiy] CEM3340 Black Friday Sale

[aankrom]

I've often wondered if, on circuits that use a diode as a voltage 
controlled resistor, if adding a 2nd diode in series would create 
something close to exponential response. I don't even know why this 
occurs to me. It's just that in the back (of the front) of my head, 
something is saying, "Hey, the math is close..." I think it's from 
seeing it done in other circuits. I've even seen three diodes in series 
- not counting diode ladder filters...
