US Patent Issued on Aug. 11 for "Architecture for DC bias canceling and gain recovery for hard disk drive fly height detection" (Italian Inventors)

ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,706,117, issued on Aug. 11.

"Architecture for DC bias canceling and gain recovery for hard disk drive fly height detection" was invented by Francesco Piscitelli (Milan), Alessio Emanuele Vergani (Milan) and Dario Livornesi (Milan).

According to the abstract* released by the U.S. Patent & Trademark Office: "According to an embodiment, a system for processing signals from a resistive sensor that monitors spacing between a disk drive head and disk surface includes a bias-canceling digital-to-analog converter and a translinear cell. The bias-canceling digital-to-analog converter generates a cancelation current equal to a bias current across the resistive sensor. The translinear cell rece...
