ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,504,449, issued on Dec. 23, was assigned to Synopsys Inc. (Sunnyvale, Calif.).
"Supply voltage droop detector" was invented by Ketul Bhogilal Sutaria (Austin, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "A droop detector includes a phase generator generating a pulse responsive to a clock signal; an edge detector generating a first signal in response to the pulse; and a time-to-digital converter that includes N time-to-digital converter units. The time-to-digital converter generates an N-bit value representative of the timing difference between the edge of the pulse and the first signal. A capacitance associated with a subset of the time-to-digit...
