US Patent Issued to Taiwan Semiconductor Manufacturing on March 18 for "Device and method for measuring a duty cycle of a clock signal" (Texas Inventors)

ALEXANDRIA, Va., March 19 -- United States Patent no. 12,253,563, issued on March 18, was assigned to Taiwan Semiconductor Manufacturing Co. Ltd. (Hsinchu, Taiwan).

"Device and method for measuring a duty cycle of a clock signal" was invented by Eric Soenen (Austin, Texas) and Alan Roth (Leander, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "A duty cycle measurement (DCM) device includes a charge pump circuit and a clocked comparator circuit. The charge pump circuit is configured to receive a clock signal that has an unknown duty cycle and to generate a capacitor voltage based on the duty cycle of the clock signal. The clocked comparator circuit is configured to receive the capacitor voltage and a ref...
