Title: WARBURG impedance
Post by OpAmp on Jan 5^th, 2006, 9:44pm

Hi,

I’m trying to model a WARBURG impedance (Usually discussed in electrochemistry) in HSPICE. Your helps are greatly appreciated.

Thanks

Perhaps you could post some links to describing the effect, or better yet, distill them to a few equations?

HSpice's dependent sources allow fairly arbitrary expressions, you just have to reduce the physics to "through" and "across" variables (through=current, across=voltage). Verilog-A (the modeling language) has a natural way of setting up these equivalences, but if you can keep things straight in your head, you should be able to work with standard HSpice.
