Hello all!
Is there an error on paga 15, figure 15. There is written 0.5LSB error, INL = 0.2LSB. Is this an error or I don't understand something?
Thanks

Yes, of course I can share with you. I have one pdf, in which you can find both configurations, caps for MSBs, resistors for LSBs, and resistors for MSB, caps for LSB. You can find the schemes at the end of pdf, data converters chapter.
you need to decrease your reqirements in the specification, or try to find out another decision, which allow to achieve your requirements. First of all you may determine can you achieve this requirements with your technology or it is absolutely impossible.
If the full-scale error is so critical for your specification, at first try to use offset concellation. Did you use an offset concellation in your ADC?
Re: CMOS LNA
I think it is almost impossible to achieve 0.9db noise with the CMOS technology, especially I mean repetition production, not experimantal samples
Re: offset cancellation
My simulation in Cadence showed that the offset cancellation using the negative feedback doesn't depend on DC level of offset voltage.

I recommend you to read this article. Hope it will help you a lot.
self calibration sar adc
Hi everybody!
Now I design a 12-bit SAR ADC with capacitor ratio self-calibration. Because technology, I use, doesn't allow to reach more than 10 bit accuracy even with the superior matchnig of capacitors.
Does anybody have experience with the ADCs with...
Re: Monte Carlo question
I think it's mean that parameter L is deeviate with standard Gauss distribution, with absolute value 0.01% from 8u.
The same for the second picture.
