Phase-locked loop bandwidth calibration |
摘要 |
A novel circuit for obtaining the bandwidth of a phase-locked loop circuit is disclosed. The circuit adjusts a phase of a signal (reference or generated), causing the phase-locked loop circuit to adjust the frequency of its voltage-controlled oscillator as it recovers a phase lock. The circuit times the duration of the recovery stage, from which the loop bandwidth may be obtained. Adjustments to the programmable portions of the phase-locked loop may then be made in accordance with design specifications.
