Other Parts Discussed in Thread: OPA388,
Hello Marek,
about your simulation for phase margin, in your schematics you connected the capacitor on the + input of OPA388 to ground while it is in parallel at the sensor.
I suppose it changes something, doesn't it?
Thanks for replies.....
Maurizio
PS: I have downloaded the PSPICE from OPA388 web page and run it in the CADENCE PSpice without get any of the behavior I have in the real circuit. Of course, the simulation I did could be not accurate....
