What is the best op amp or in amp to dc offset a signal from cmos?

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 Azami,

    Basically, both types of amplifiers can meet your requirements. But InAmp would be, in my opinion, an irrational choice, because this type of amplifier is designed to receive a differential signal and provides a high level of CMRR. This is not what you need for your design.

    Do you have any initial ideas? Can you share them? Looking at the circuit diagram is much easier to analyze
