1. A disk drive read circuit comprising:
a read element for generating a read signal; and a sense amplifier comprising an input terminal coupled through a first capacitor to the read element and an output terminal coupled through a second capacitor to a first end of a transmission line, wherein:
a second end of the transmission line is coupled to a preamplifier; andthe sense amplifier is for amplifying the read signal,wherein the transmission line provides at least one of a bias signal to the read element and power to the sense amplifier. |
