Title: diode
Post by SAM_K on Nov 2^nd, 2010, 11:20pm

how do i increse the scalability(varying w,l etc.) of the four regions of a diode if im doing an empirical fit with decent accuracy in VeriolgA.

I'm not quite sure how Verilog-A is involved here -- do you have a compact model description of a diode written in Verilog-A?

If you're trying to fit four regions, then you'd better have equations for the four different regions. Diode models built into commercial simulators typically have a couple saturation currents: forward, reverse/breakdown, tunneling.

yes I ll go in this direction as well:
=> I would take this descripion as a starting point:

, and implement all the features I d need using equations derived from the physics to have a parametrizable model.
