ALEXANDRIA, Va., Sept. 24 -- United States Patent no. 12,744,538, issued on Sept. 22, was assigned to QUALCOMM Incorproated (San Diego).

"Phase interpolator linearity through adjustments to unit current step" was invented by Seuk Son (San Diego), Ying Duan (San Diego), Qinqing Cao (San Diego) and Abhay Dixit (San Diego).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase interpolator includes a plurality of source-coupled transistor pairs and a plurality of current sources. The plurality of source-coupled transistor pairs may be configured to receive different phase shifted versions of an input signal. A differential output of each source-coupled transistor pair may be coupled to a differential output of t...
