BACKGROUND We have held many successful Summit meetings across Asia in previous years. This year we are adding a meeting in Taipei where many national and international high technology companies have operations. Presentations from past events are available at our Summit archive: http://www.eda.org/pub/ibis/summits/ Our objective is to reach out internationally to communicate with the local experts and to learn of regional concerns. CONFERENCE LANGUAGE The conference language is English, but we will plan for technical translations in English and Chinese. So presenters can optionally deliver in Chinese as long as an English version of the material is available. IBIS SUMMIT This meeting will be conducted as a formal IBIS Summit Meeting. Presentations will be archived in an electronic format on our Summits site, and minutes of the meeting will be issued. However, no formal decisions requiring votes will be planned. CALL FOR PARTICIPANTS People involved in IBIS and interconnect model development, EDA tool development, and digital circuit design are invited to participate in the Summit meeting.

The problem is that you may get different result= s

Hi,

       For the calculation= of C_comp by AC sweep, we apply an AC signal along with some DC voltage. What should be the value of this DC voltage to get correct C_comp value?

 

Thanks in advance.
