Most if not all of them concentrate on PIN diodes but I'm sure the same modeling techniques would apply to non PIN diodes. Search in the IEEE journals related to power electronics if you're interested (an example is http://ieeexplore.ieee.org/document/349750/).

I have several dozen on the subject. I have developed a fairly simple modeling method that seems robust. All I need is data from specific devices to test my method. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Thinking outside the box... producing elegant solutions.

That work was set aside last August because I wasn't quite happy with it... so I pursued other items. I find that approach often refreshes my mind, because, when I went back to it, I realized a major simplification that escaped me previously. So I'm happy. Someone will provide data so I can compare measured versus model, then I will publish; but I feel quite certain I've cracked the nut. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Thinking outside the box... producing elegant solutions.
