Re: charge-pump AGC
Hi,
What I would suggest to you is first find the articles and journals which discuss the concept and mechanism of AGC and Charge pump circuit separately. Then when u understand the operation of the individual circuit clearly, later you can able integrate them together by knowing which point to control by applying the feedback control method at the right node as we know the charge pump works on the concept of voltage boosting and so on.
Thanks,
