PHASE-LOCKED LOOP WITH LOOP GAIN CALIBRATION, GAIN MEASUREMENT METHOD, GAIN CALIBRATION METHOD AND JITTER MEASUREMENT METHOD FOR PHASE-LOCKED LOOP |
摘要 |
The invention provides a phase-locked loop with loop gain calibration and methods for measuring an oscillator gain, gain calibration and jitter measurement for a phase-locked loop. The method for measuring an oscillator gain of a phase-locked loop includes the steps of providing a varying code at an input end of the oscillator; outputting excess reference phase information by a reference phase integral path and outputting excess feedback phase information based on the varying code by a feedback phase integral path; and obtaining an estimated gain information of the oscillator based on the excess reference phase information and the excess feedback phase information. |
