Abstract
A preamplifier system includes an amplifier stage having at least one feedback network. The feedback network has a feedback resistance that may be adjusted to improve a frequency response of the preamplifier. A feedback control system is operative to set the resistance of the feedback network as a function of a resistance value of an associated read/write head.
