offset cancellation

using negative feedback in baseband amplifiers reduces the DC-offset. does the accuracy of this DC-offset cancellation depend on the magnitude of the input DC-offset voltage? I mean, the higher the input DC-offset voltage is, the better the negative feedback works?
 

Re: offset cancellation

My simulation in Cadence showed that the offset cancellation using the negative feedback doesn't depend on DC level of offset voltage.

I recommend you to read this article. Hope it will help you a lot.

Thank u for the book
