The invention discloses a phase-locked loop frequency synthesizer structure for improving in-band phase noise performance. The phase-locked loop frequency synthesizer structure consists of two loops, namely a coarse tuning loop and a fine tuning loop, wherein the coarse tuning loop is used for selecting different frequency control words to realize the frequency locking of the loop, the fine tuning loop is used for realizing the phase locking of the loop. When in a locking state, the coarse tuning loop can be turned off and only the fine tuning loop works. By utilizing the structure provided by the invention, the problem that the in-band phase noise of the traditional structure is restricted by a frequency divider can be solved. By introducing the fine tuning loop, the noise of the frequency divider can be effectively reduced in the locking state and the in-band phase noise performance of the phase-locked loop frequency synthesizer can be improved.

The invention discloses a threshold value offset calibration method applied to a time domain comparator. The output of the time domain comparator of which the input end is short-circuited is detected, rough regulation control words for zero-crossing detection are regulated at first and then fine regulation control words for the zero-crossing detection are regulated until threshold value offset is decreased to be in a calibrated error range. The method comprises the following steps of: resetting the rough regulation control words and the fine regulation control words to be initial values, and short-circuiting the input end of the time domain comparator; regulating the rough regulation control words for corresponding zero-crossing detection according to a result of the comparator until the comparison result is changed; regulating fine regulation control words for corresponding zero-crossing detection according to the result of the comparator until the comparison result is changed; and disconnecting the input end of the comparator to finish the calibration of the threshold value offset. The method has the characteristics of not influencing the speed of the comparator, not increasing additional power consumption and only requiring once working after power-on. After the multiple cyclic feedback regulation of the control words, the threshold value offset of the comparator can be greatly decreased and a clock cycle required by the finishing of the calibration can be effectively controlled.
