    corner simu vs Monte carlo

    Thanks to all of you for your inputs. I do know all this differences, however I was not able to get something on paper which shows the comparison between the 2 ways of doing things. In my past experience, whenever you managed to do a design which even in the worst corners fitted the...

    Establish Conference for IC circuit design focus in Mix Sign

    Re: Establish Conference for IC circuit design focus in Mix You can try the courses from Lausanne in Switzerland. Check EPFL on the web.

    corner simu vs Monte carlo

    corner analysis vsmonte carlo I need to know if anybody can provide some links towards books or artciles which can explain ina formal way the difference between corner and MonteCarlo simulations. As far as i know corner simualtions are 'the real deal" due to the fact they are showing the...

    H-bridge keeps blowing up

    It would help to get schematics and datasheet for your drive. Normaly you should have some sort of protection that should allow a safe on/off. I might be able to help if you can provide schematics Regards

    Full Differential and Single Ended

    fully differential comparator design It would also help if you don't realy need rail to rail signal through your high speed chain. You can have only at the output stage something that will be rail-to-rail.

    Is the common centroid method obsolete ?

    Re: Common centroid Correct. That will be impossible almost to match they vary in a different way

    Does Matching depend on process?

    Re: Matching The ABBA has the advantage of taking care of the x,y mismatches. Having a common point which is in the middle of BB, will insure that the average deviation of the 4 transistors is the same. first B has more than first A, second B less then second A in average they have the same...

    What are the applications of CMOS and BiCMOS devices?

    Re: Why CMOS I beg to differ. For bipolar they already have transistors with cut-off frequency over 150GHz. However this is SiGe

    Efficiency of Analog IC Designing

    I think you should design, follow the layout and then measure the outcome in the lab. You will be anyway the one who knows the best how to test his own work...especially if there is something wrong, You should find the reason and the solution. Only then you are complete. But again, this is my...

    Efficiency of Analog IC Designing

    For all of you some questions remain : How can you give guidelines for layout if you have never made one? How can you help the designer if you have never made design? On top of that, if you have designed, made different layouts and then measured in the lab the outcome for all variants, you can...

    Efficiency of Analog IC Designing

    it depends a lot on the continent and company as well. I have always done my own layout for about 10 years in Canadaand Europe. Now, I am working back in Europe and somebody else is doing the layout. And it is a huge mess most of the time...because they can't follow what you want and you can't...

    What are the applications of CMOS and BiCMOS devices?

    Re: Why CMOS CMOS is matured for a lot of high volume consumer applications. However, for specific cases (high speed com, very precise structures/references etc) you will need BiCMOS (SiGe, GaAs, and Si)
