Title: VBIC HBT modeling Post by jiklo on May 28th, 2006, 12:15pm HI, I'am new here, and new in design. Using a Orcad 9.2. I'am looking to investigate VBIC model SiGe HBT parameters for my work (bachelor work). The main option of HBT is cutoff frecuency shuold be more than 47 Ghz. So, those parameters i need to use in Pspice model editor. Could you send me. Thank you. |
Title: Re: VBIC HBT modeling Post by ACWWong on May 29th, 2006, 4:11pm you might try: http://www2.fht-esslingen.de/institute/iafgp/neu/VBIC/index.html You can download some conversion programs for Gummel-Poon to VBIC and vice versa. Also useful are the decriptive documents and the verilogA example. |
Title: Re: VBIC HBT modeling Post by Geoffrey_Coram on May 30th, 2006, 4:20am There's also a VBIC web page on this site: http://www.designers-guide.org/VBIC/ It looks to contain the same information as the link in the previous post (FHT-Esslingen). |
Title: Re: VBIC HBT modeling Post by jiklo on May 31st, 2006, 7:35am But these is a Verilog net list. How to take a necessary data from there? |
Title: Re: VBIC HBT modeling Post by ACWWong on May 31st, 2006, 8:55am The verilogA code is a behavioural model of VBIC device model written in the verilogA language. You can get the equivalent circuit that is used to model a HBT in VBIC from it and some typical values used for the VBIC parameters and contrast it with the SGP (std GummelPoon) model. But a picture is much better so look at : http://www.designers-guide.org/VBIC/documents/equivalentCircuit.html It is not clear what you want to do, but if you are looking for some SGP or VBIC model parameters for actual transistors, they are supplied by IC vendors. But in most cases they will only supply SGP. You use the conversion programs on the VBIC link to translate model parameters between SGP & VBIC and fiddle with the VBIC extension parameters to see their effect, if that is what you want to do.... |

Title: Re: VBIC HBT modeling Post by Geoffrey_Coram on Jun 16th, 2010, 5:49am Did you try this site itself? Clicking Verilog-AMS in the header bar, then looking under Semiconductor Models, I found: http://www.designers-guide.org/VBIC/index.html |
