| 摘要: | An improved adaptive frequency calibration(AFC) has been employed to implement a fast lock phaselocked loop based frequency synthesizer in a 0.18μm CMOS process.The AFC can work in two modes:the frequency calibration mode and the store/load mode.In the frequency calibration mode,a novel frequency-detector is used to reduce the frequency calibration time to 16 us typically.In the store/load mode,the AFC makes the voltage-controlled oscillator(VCO) return to the calibrated frequency in about 1μs by loading the calibration result stored after the frequency calibration. |
