Would any people like to introduce me some good book or material,which
describe the detail of DC offset compensation feedback of
multistage-amplifier?
I am currently working on high-speed limiting amplifier, however still
not clear about the usage of the DC feed-back. Personally, I think it
make the circuit operating point insensible to process variation. Right?
Some paper integrated the DC-feedback path on-chip, some put it outside and make it tunable. Which way is used for which reason?
Can any one give me a clear picture of it? Any material or paper
introduce it will be very helpful to me, thank you!
