ALEXANDRIA, Va., Jan. 13 -- United States Patent no. 12,523,745, issued on Jan. 13, was assigned to NXP B.V. (Eindhoven, Netherlands).
"Injection current modulation for chirp signal timing control" was invented by Piotr Gibas (Eindhoven, Netherlands) and Tarik Saric (Eindhoven, Netherlands).
According to the abstract* released by the U.S. Patent & Trademark Office: "A radar system injects a calibrated current at a signal generator during a reset portion and acquisition portion of each chirp period. The signal generator employs "gear-switching" to reduce PLL bandwidth during an acquisition phase and to increase the phase lock loop (PLL) bandwidth during a reset phase. By employing gear switching to change the bandwidth of the PLL circuit d...
