Reinier,
Sounds interesting. Could you also
make a very simple opamp with the
output voltage limited to the
supply voltages? I sometimes get
Mega Volts in my circuit on 1 Volt
transients at the inputs.
Yes, the thing I have in mind would do
that. Below is a list prepared for
someone else who asked about this
offline:
I've in mind to model GBW, AOL, slew
limit, voltage and current noise and
corner frequencies for each(But not
model noise from input impedance
imbalance like from JFET input
products), dynamic current draw from
each rail, output voltage range,
output current limit, and input bias
current. That can all be modeled in
the modeling methodology used in the
SMPS products one one internal node.
Doing the real small signal transfer
above the dominate pole requires
more nodes. For example, the LT1028
can be done with two more nodes.
CMRR would not be particularly
modeled, but it would be non-zero.
