Abstract
A power regulation system for a read channel of a data storage assembly includes a first voltage regulator for supplying power to the front-end decoder and a second voltage regulator for supplying power to the back-end codec. The second voltage regulator may conserve power reduce supply voltage to the back-end codec when the codec operates at a lower sampling frequency. The second voltage regulator may additionally increase supply voltage to the back-end codec in conjunction with an increase in sampling frequency. The system may additionally include a third voltage regulator for supplying a memory structure of the read channel with only the minimum required operating voltage to prevent leakage power.
