hi
i generally have two questions about a 10bit sar adc
1. is offset cancellation essential when designing the comparator of the adc
using the archetecture of a preamp with latch?
2. is it need trimming or calibration to design a 10bit sar adc?
if the offset of the comparator must be cancelled, do you have any good ideas to elliminate this offset? i mean some good archetecture to share. or the preamp shoule be designed with two amp?
do anybody have some paper to illustrate the split of the cap array of dac in detail?
pls share with me
thank you all
best regards to you
