Then, why does one need the extra 30+ dB from the ADC in this sensor?Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-65197034857184713262011-02-24T19:11:41.499+02:002011-02-24T19:11:41.499+02:00Isn't it more efficient to use a sigma delta w...Isn't it more efficient to use a sigma delta with inherent multiple sampling instead of folding or whatever other ADC architecture? And how can they obtain 19bit of resolution with a single ended(!) column level adc? Do they use special calibration techniques? Very curious to read the paper...adihttps://www.blogger.com/profile/15758761072546922563noreply@blogger.com
