US Patent Issued to Intel on July 15 for "Notch filter calibration in LC oscillators for supply noise rejection" (American, Israeli Inventors)

ALEXANDRIA, Va., July 16 -- United States Patent no. 12,362,704, issued on July 15, was assigned to Intel Corp. (Santa Clara, Calif.).

"Notch filter calibration in LC oscillators for supply noise rejection" was invented by Noam Familia (Modiin, Israel) and Vadim Levin (Folsom, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Embodiments herein relate to an apparatus and method for calibrating a notch filter which filters a power supply signal for a voltage-controlled oscillator (VCO). In one aspect, a control circuit performs a number of calibration cycles for the filter to determine a value of a calibration code for the filter which minimizes a change in a frequency of the output signal of the VCO due ...
