ALEXANDRIA, Va., July 16 -- United States Patent no. 12,362,902, issued on July 15, was assigned to Microsoft Technology Licensing LLC (Redmond, Wash.).

"Phase interpolator (PI) with clamping circuit to limit operation to range having optimal integral non-linearity and related methods" was invented by Ping Lu (Cary, N.C.) and Minhan Chen (Cary, N.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase-interpolator (PI) circuit generates an interpolated clock to capture data in a capture circuit at a target phase in a phase range between two reference clocks based on an interpolation code within a range of interpolation codes is described. A clamping circuit coupled to the PI circuit provides an interpolati...
