Abstract :
A fast lock digital phase-locked-loop (PLL) frequency synthesizer for wireless applications is reported. The main advantages of the architecture include small area and digitally selectable frequency resolution. Also, a fully digital solution to reducing the phase lock time is introduced. This work is also supported by a nonlinear analytical analysis of the locking mechanism for PLLs.
