Hi fenngou,
Kdco although known, is not constant and varies quite a bit with process, voltage and temperature. By normalizing it, we make sure the variations do not impact the pll operation as long as we estimate its value correctly. Gain estimation is also straight forward because, unlike...
Thanks RC, but can you elaborate on digital PWM chop? I don't exactly know how that works and googling wasn't of much help either!
In my question I meant some kind of a time to digital converter that quantizes the input time differences in terms of the number of fixed time delays, lets say an...
I would like to know why fractional spurs are more of a problem in All digital PLL when compared to more traditional charge pump PLLs. I'm guessing it must be because of the sampling nature of the TDC . Are the fractional spurs that fall beyond the reference frequency folded back due to...
Dear all,
I am new to this forum and I am not aware of many rules around. Excuse me if this is not the right place to ask my query.
I am a masters student at TU Delft and I am interested in RF IC design. I would like to do a research internship this summer to get some valuable experience. I...
