Hi Curt,
I apologize for my late reply. I retrieved and reviewed
these papers, good stuff here!
For higher frequency response, I will assume battery is "AC
open", and focus on PDN for this aspect.
For lower frequency response, I will consider battery model
also.
Thank you so much for your assistance!
Regards,
Ivor

Subject: [SI-LIST] Battery impedance
Hi all, I'm doing PDN analysis on mobile battery powered device and
considering how to model the battery as voltage source. Data sheets for these
types of batteries typically have specification for DC impedance and/or AC @
1KHz impedance, but I need impedance profile data to several MHz.
Any ideas or resource links about this? Thanks, Ivor
