    Opening GDS file in Cadence

    how to open .gds file Is your .gds file in a Windows OS partition ? If yes, you should check if that partition is a NTFS one for you to be able to open the .gds from a Linux environment (where Cadence is installed) .. By other hand, you simply can copy it in one of your Linux partitions (for...

    MOS A's and P's miscalculated from w&l parameters in cad

    Hi all.. In my design I'm using nmos4 and pmos4 active devices from AMS DKIT 3.70 PRIMLIB library. As shown in the figure, when I try to edit their properties in Virtuoso Schematic, their area and perimeter fields are recalculated for w and l values (and are not editable for that reason). So...

    determine ADC bit and speed

    Hi fanshuo: It's not common to AD convert signals at several GHz because of the very difficult design issues related to circuits operating at such frequencies... For that reason, it's easier to convert those signals down to baseband before using the ADC, where the important topic for its sample...

    How to improve SR? What is the 3dB BW of voltage follower?

    SR and 3dB BW question If u are working with differential topologies, take care about a symmetrical slewing of the output stage because sometimes one of the branches is faster than the other one.

    About the degree of parallelism of a time-interleaved ADC

    Hi: It's very simple: I can't understand why in fig 3 of the well known paper "A 10-bit 200-MS/s CMOS Parallel Pipeline A/D Converter" of Waltari and Sunamen, where the authors study the effect of the degree of parallelism on the current consumption for a 10 bit ADC, the linear part of the...

    Again with the serial mouse

    Hi all, please help me with this trouble: I installed LINUX Fedora core (kernel 2.6.11) and I haven't been able to make my 3-buttons serial mouse to work with this OS. I've already asked for help before at this forum and somebody recommended to me looking at some sites, and I did.I followed the...
