ALEXANDRIA, Va., March 26 -- United States Patent no. 12,261,616, issued on March 25, was assigned to MEDIATEK SINGAPORE PTE. LTD. (Singapore).

"Noise shaping in digital-to-analog converters using randomizing encoders" was invented by Timothy Perrin Fisher-Jeffes (Cambridge, Great Britain) and Nathan Egan (Burlington, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for compensating high-speed digital-to-analog converters (DACs) for static mismatch are described. In ideal circumstances, the current sources of a DAC are identical to each other, leading to a frequency response presenting a relatively flat noise spectrum. In the presence of mismatch, however, the response creates unwanted spuriou...
