hello,
i am trying to model an LDO as a norton equivalent network. i can run an .ac simulation to get the output impedance vs frequency and export it as a file, but am having a difficult time figuring out how to attach this file (with magnitude/phase information) to a current source and then use that norton equivalent network in my simulations. i was hoping it would be something akin to including a noise file for a vdc source, but i haven't found a way to do so. is this even possible?
many thanks in advance.
