ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,387,756, issued on Aug. 12, was assigned to STMicroelectronics International N.V. (Geneva).

"Method of operating a voice coil motor and corresponding control circuit" was invented by Michele Boscolo Berto (Milan) and Ezio Galbiati (Agnadello, Italy).

According to the abstract* released by the U.S. Patent & Trademark Office: "Embodiments provide a method of operating a voice coil motor via a transconductance loop. The method includes detecting an actual value of a supply voltage of the transconductance loop. An offset compensation signal of the transconductance loop is produced as a function of the detected actual value of the supply voltage based on a relationship between offset valu...
