ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,253, issued on Nov. 25, was assigned to Taiwan Semiconductor Manufacturing Co. Ltd. (Hsinchu, Taiwan).

"Coarse-mover with sequential finer tuning step" was invented by Tsung-Hsien Tsai (Taoyuan County, Taiwan), Jason Hsu (Hsinchu, Taiwan) and Ruey-Bin Sheen (Taichung, Taiwan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A tuning array selection circuit, together with a decoder and a voltage controlled oscillator (VCO), can be employed to overcome some disadvantages of previous methods of phase locked loops. For example, a VCO can include a coarse tuning array and a fine tuning array. A coarse tuning array can be used to tune a VCO to generate a sig...
