US Patent Issued to Apple on Dec. 30 for "Current mode time-to-digital converter-based power detector" (California Inventors)

ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,510,571, issued on Dec. 30, was assigned to Apple Inc. (Cupertino, Calif.).

"Current mode time-to-digital converter-based power detector" was invented by Ankit Srivastava (San Diego) and David M Signoff (Santa Clara, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A power detector includes a first current mirror that receives an input signal and generates a mirrored input signal, a first oscillator that reverses a first current of the mirrored input signal based on a voltage of the mirrored input signal reaching a threshold, and a first counter that generates a first count of each period generated by the first oscillator. The power detector also i...
