Hi Saikat,
I have some questions:
According to the definition of DR, the lowest possible amplitude of input voltage is defined by maximum of input-referred noise voltage. My question is - why is it not dictated by the linearity range of OTA? Because, trying to reduce the input amplitude after a certain value will violate the saturation criterion of the input transistor of the OTA.
May be I am wrong. Please clarify. Actually I am in real confusion about how to measure the DR. If you know, please suggest me some relevant literatures which explains it from the basic level.
regards
Sam
