US Patent Issued to Google on Aug. 25 for "Random modulation of charge-pump noise phases" (California Inventors)

ALEXANDRIA, Va., Aug. 25 -- United States Patent no. 12,720,226, issued on Aug. 25, was assigned to Google LLC (Mountain View, Calif.).

"Random modulation of charge-pump noise phases" was invented by Qingfei Chen (Mountain View, Calif.) and Kwang Oh Kim (San Jose, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques and apparatuses are described that implement random modulation of charge-pump noise phases to reduce structured noise induced by the charge pump. In an example aspect, a correlated double sampling (CDS) circuit is coupled to a pixel array including at least one pixel circuit. The CDS circuit receives an input signal generated by the at least one pixel circuit from the pixel array and ...
