Abstract
A new frequency synthesizer based on all digital phase-locked loop is proposed to realize the phase noise tracking compensation and reduce the complexity of the all digital phase-locked loop. It uses an digital phase-frequency detector and a nonlinear phase/frequency decision circuit as well as a digitally-controlled oscillator with a low complexity to significantly reduces the hardware complexity. At the same time,the proposed architecture can achieve good noise tracking and fast phase/frequency acquisition and high frequency resolution(approximately 6 kHz)and large linear frequency tuning range. The experimental results show that the proposed frequency synthesizer can achieve a programmable loop bandwidth from 100 kHz to 6 MHz and an excellent in-band phase noise tracking performance.关键词
