Error protection method, TDC module, CTDC module, all-digital phase-locked loop, and calibration method thereof |
摘要 |
An error predict code is added into a cycle signal for raising precision of an output signal of a time-to-digital (TDC) decoder. A cyclic TDC (CTDC) is specifically designed within a phase-frequency detector (PFD)/CTDC module of an all-digital phase-locked loop (ADPLL) for enhancing loop bandwidth calibration of the ADPLL. A calibration method is used on the PFD/CTDC module for enhancing the loop bandwidth calibration of the ADPLL as well.
