Design Considerations for Autocalibrations of Wide-Band ΔΣ Fractional-N PLL Synthesizers
Autocalibration of VCO frequency and loop gain is an essential process in PLL frequency synthesizers. In a wide tuning-range fractional-N PLL frequency synthesizer, high-speed and high-precision automatic calibration is especially important for shortening the lock time and improving the phase noise....
