摘要： An automatic frequency calibration apparatus and a method thereof for a phase-locked loop based frequency synthesizer are disclosed. The apparatus includes a frequency-to-digital converter configured to convert a frequency of a VCO output signal to a first digital value, a target value setting section configured to provide a second digital value corresponding to a target frequency, and a finite state machine configured to calibrate the frequency of the VCO output signal by using the difference of the first digital value and the second digital value. Accordingly, the calibration speed and a frequency resolution of the automatic frequency calibration apparatus in a frequency synthesizer may be enhanced.

摘要： A frequency synthesizer and an automatic calibration device are disclosed. An automatic calibration device for a phase-locked loop based frequency synthesizer includes: a frequency-to-digital converter for converting a frequency of a signal outputted from a voltage controlled oscillator into a first digital value; a frequency difference detector for calculating a difference between the first digital value outputted from the frequency-to-digital converter and a second digital value corresponding to a target frequency; an automatic frequency calibration logic for selecting an optimal control code for a capacitor bank such that an output frequency of the voltage controlled oscillator is closer to the target frequency; and a loop bandwidth calibration logic for tuning a charge pump gain such that a loop bandwidth is kept constant in the optimal control code using the frequency-to-digital converter. Thus, the calibration speed can be increased, and the loop bandwidth can be kept constant within the output frequency range.
