US Patent Issued to Microsoft Technology Licensing on March 31 for "Phase interpolator (PI) including weighted summing circuit and related methods" (North Carolina Inventors)

ALEXANDRIA, Va., March 31 -- United States Patent no. 12,592,687, issued on March 31, was assigned to Microsoft Technology Licensing LLC (Redmond, Wash.).

"Phase interpolator (PI) including weighted summing circuit 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: "To compensate for the non-linearity of a phase interpolation (PI) circuit, the interpolation clocks of two PI circuits receiving different interpolation codes may be summed. However, even if the non-linearities of the interpolated clocks have opposite polarities, they may have different magnitudes causing some non-linearity. A weighted summing PI that sums interpolat...
