摘要: A method and system for high bandwidth, gain offset compensation in a read channel integrated circuit includes zeroing the analog signal applied to path at first location prior amplifier which has bandwidth magnitude characteristic with frequency boost; coupling from second larger than having roll-off; further storage device feeding back stored apply boost of compensate roll-off characteristic; decoupling removing path.
