varactor accumulation inversion

Dear all,

Could anyone introduce a book to describe in detail about the work mechanism of the Varactor? such as how to form inversion, deplection and accumulation region.

I have seen the materials and show the graph of the capacitance of the varactor Vs the Vctrl. It shows the capacitance value of the accumulation region and the inversion regsion is the same. However, I have tried to simulate it and it found that there are some different capactirance value. WHY?

Best Regards,

wccheng
 

Related to your request, two good ebooks you can find on the Upload/Download forum:
RF/Microwave Circuit Design for Wireless Applications – U. Rohde (chapter 2 – Models for active devices)

and
Nonlinear Microwave And RF Circuits – Stephen Maas (check page 582 for index)
 

You can find in Agilent, mini circuits, microceramics, microsemi catalogs
