Phase jitter dynamics of first-order digital phase-locked loops with frequency-modulated input [PDF]

open access: yes, 2008
IEEE International Symposium on Circuits and Systems (ISCAS), Seattle, USA, 18-21 May 2008Inherent to digital phase-locked loops is frequency quantization in the number-controlled oscillator which prevents the loop from locking exactly onto its reference

System Level Modeling and Verification of All-digital Phase-locked Loop

open access: yes, 2015
In wirelesscommunication systems, a local oscillator (LO) aims at demodulating radio-frequency signals into baseband signals. The performance of these signals determines the quality of communications which is highly affected by the phase accuracy of ...

ON THE DESIGN OF ADAPTIVE-BANDWIDTH ALL-DIGITAL PHASE-LOCKED LOOPS

open access: yes, 2011
The second-order adaptive-bandwidth all-digital phase-locked loop (ADB-ADPLL) is designed and analyzed by using a new design procedure. Based on a discrete-time analogy of a continuous-time PLL (CTPLL) with the z-transform, the design criterion of the ...

A 5GHz 90-nm CMOS all digital phase-locked loop

open access: yes, 2009
An all digital phase-locked loop (ADPLL) has been implemented in a 90-nm CMOS process. It uses a phase frequency detector (PFD) connected to two time-to-digital converters (TDC). To save power the TDCs use uneven delay time in the delay line cells.
