US Patent Issued to Analog Devices on Dec. 2 for "Clock doubler with correction for output clock cycle and clock duty cycle" (New Jersey Inventor)

ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,487,629, issued on Dec. 2, was assigned to Analog Devices Inc. (Wilmington, Mass.).

"Clock doubler with correction for output clock cycle and clock duty cycle" was invented by Xuesong Jiang (Princeton, N.J.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A synthesizable clock doubler is disclosed. The clock doubler is implemented using unique combination of logic cells from a standard cell library. At the core of the clock doubler is a high-frequency ring oscillator that generates timing information for clock measurements. Replica ring oscillators are used to generate programmable delays for the correction of the output clock imperfection, such as cycle-t...
