US Patent Issued to MediaTek on March 3 for "High-speed hardware-based DVFS system using frequency lock loop and on-die voltage controller" (California Inventors)

ALEXANDRIA, Va., March 3 -- United States Patent no. 12,566,463, issued on March 3, was assigned to MediaTek Inc. (Hsinchu City, Taiwan).

"High-speed hardware-based DVFS system using frequency lock loop and on-die voltage controller" was invented by Anshul Varma (San Jose, Calif.) and Hsin-Chen Chen (San Jose, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A voltage controller circuit is provided for dynamic frequency and voltage scaling. The voltage controller circuit receives an error signal indicating a frequency error and a code error. The frequency error indicates a first difference between a target frequency and an actual frequency generated by an oscillator, and the code error indicates a secon...
