ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,772,354, issued on Oct. 20, was assigned to Silicon Laboratories Inc. (Austin, Texas).

"Timing based signal valley detection" was invented by Bhavna Rachuri (Austin, Texas) and Michael D. Mulligan (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "An embodiment of a timing-based signal valley detection technique improves efficiency and reduces electromagnetic emissions due to ringing by controlling the off-time of a power switch in an LED driver or power converter application. The timing-based technique estimates a time of occurrence of a valley in the drain voltage of the power switch. The timing-based technique uses an analog comparator to ...
