If you had two separate 10x 1-stage amplifiers cascaded you would get 100x gain. The first amplifier offset would dominate because the second amplifier's offset would be divided by 10x.
However if I have a 100x 2-stage amplifier (both stages in the same feedback loop), what happens to the second stage offset? What is the advantage of having both stages inside the same feedback loop rather than having two separate 10x amplifiers?
Thanks
