Abstract
A method and circuit for selectively timing amplifier stages of a multi-stage reader amplifier for a hard disk drive system. The reader amplifier includes a first stage, second stage and third stage coupled in series. The method includes the steps of powering the first stage, delaying the enabling of the second stage, and delaying the enabling of the third stage, in order to reduce excursions on the third stage output signal. The circuit includes a logic circuit for successively enabling the second and third amplifier stages.
