thank u all for your contributions,
i am interested in the same questions as snoop835.
however, i am new to the ADC buisness, my requirements are as follows :
10 bit, 4ksps, <1mW, die are around .12 mm², AMS .35µ.......in <5 months
i am confused between an SAR ADC and a ΣΔ, but i don't think i can deliver a ΣΔ in that short period, given the fact that this is my first converter project.
so i guess its the SAR ADC, but how do i go about realising it, books only provide the system level blocks that we all know, the papers where nice, but still how do i size the caps and how to implement the switch arrays and the SAR itself
many thanks
Added after 4 minutes:
here is a paper the grabed my attention,
i think it should be quick to implement but still i don't know how to implement the switching array.....
any ideas or references are much apprectiated.
many thanks
