Cmos and ccd have a dc offset that must be eliminted before input to an adc.
I am looking for the best way to dc offset the cmos signal wothout adding noise.

Hi,
Thank you for your recommandations.
Actually i would like to you use AD8274 or AD8271 difference amplifier.
Should i use buffer amplifier (like LT1818) at inputs?
Hi Azami,
You can always find out if you need to use a buffer amplifier yourself, just by studying the specification of your CMOS device. The maximum output current must be specified there.
