Title: how stages op should be used in regulator?
Post by Robert on Jul 20^th, 2006, 6:38pm

hi, everyone!
i am doing a TIA project now, and i need a regulator with high psrr and low noise figure, i have designed a bandgajp voltage reference with a psrr around 70dB, but i am confused about the op, shoud i take the multi stage structure to obtain high gain and wide bandwidth, then the stability would be a problem, or shoule i take single stage structure, then how to achive high gain and wide bandwith at the same time? you guys would how to solve this problem, i really need your reply, thanks in advance.
