Application: Injection current modulation for chirp signal timing control (Patent ID: US20230417872A1)

The patent by NXP Semiconductors NV describes a radar system that optimizes efficiency by employing gear-switching to adjust the bandwidth of the phase-locked loop (PLL) circuit during different phases of each chirp period. This adjustment reduces the length of the reset period, enhancing radar system performance while maintaining efficiency. The method involves calibrating a chirp injection current profile during a calibration phase and generating a frequency chirp based on this profile during an acquisition phase, with the PLL operating in high and low bandwidth modes during these phases, respectively.

Furthermore, the patent details a frequency chirp signal generator for a frequency-modulated continuous-wave (FMCW) radar system. The generator includes a chirp timing engine to calibrate the injection current to capacitors of the PLL during a calibration phase and an injection digital-to-analog converter (DAC) to generate the calibrated injection current during a chirp sequence. The generator adjusts capacitance values of capacitors during different phases of the chirp sequence and provides varying injection current values to the PLL accordingly. Overall, the patent focuses on optimizing radar system efficiency and performance through precise calibration and adjustment of the PLL bandwidth during different phases of operation.
