Compositions and methods are disclosed for automated storing, tracking, retrieving and analyzing biological samples, including dry storage at ambient temperatures of nucleic acids, proteins, and cells using a dry storage matrix that permits recovery of biologically active materials. The mechanism uses a feed-forward technique that can be used in a multi-stage scheme to perform both DC compensation and amplitude adjustment of an input signal for use by subsequent processing stages. This arrangement enables a boosted voltage HV to quickly rise from 0 V to a standby voltage, thus desirably shortening an initial access permission time at the power supply ON time or at the reset time. Still further, the range of works is expanded to enable deskwork and the like.
