That was a pretty good quicky Genome came up with for modeling the
supply current of an opamp - for the problem a hand. In case you
missed it, here it is:
|
| .-. I(D1)
+---------(-->
-------------+
| '-' |
| D1 |
|\| +----->|--+ |
-|-\ | | ___ |
| >----+ +--|___|----+-----+
-|+/ | | | |
|/| | | | |
| +-----|<--+ | |
| D2 | ===
| .-. | GND
+---------(-->-------------+
| '-' I(D2)

Works for modeling the current once the diode turns on but there's
bad crossover distortion.
Take the circuit from the "strange amp - MVC-324X.JPG - T600amp.jpg"
thread. Ok, don't take it. It's supposed to be an amp, not a switch.
So using the diodes to separate source and sink currents works, but
you get that distortion.
How can we model the supply current without the diode distortion?
