Greetings,
The cmdmprobe is intended for use with differential input, differential
output operational amplifiers and OTAs. See the following append
for an example of how to use this component in a testbench,
http://www.designers-guide.org/Forum/YaBB.pl?num=1268207804The example testbench also includes the setup for the input signal
sources. There is one additional point to keep in mind, to test the
common-mode loop characteristics set the probe value to 1, to
test the differential-mode characteristics set the probe value to -1.
Best Regards,
Sheldon
