Abstract :
This paper examines several transfer curves of the phase detector in a digital phase-locked loop and illustrates the benefits of applying non-linearity to the phase transfer characteristics. Taking advantage of the programmability of the digital implementation, the proposed technique shows a better trade-off between the acquisition speed and the steady-state dithering jitter performance.
