diode compression + opamp (not diode compression opamp :P)

I once posted about this on a low traffic section, the diode compression opamp.

Basically it is the same diode compression technique used in the Vulcan. The upper resistor must be adjusted to get around vcc/2 at pin+.

It's been years since I draw something like this with characters...

Have you seen AACircuit (http://www.tech-chat.de/aacircuit.html)?  It is a program for drawing circuits and components as ASCII chars.

BTW, thanks for the diode compression opamp idea!
