电荷泵锁相环的z域建模
Charge-pump phase-lock loop's z-domain modeling
摘要
Abstract
With the rapid development of communication industry, the charge-pump phase-lock loop (CP-PLL) was popularized gradually. In this paper, according to the properties of CP-PLL circuit, the sample hold device was adopted to imitate the behavior of the circuit. A new CP-PLL z-domain model was obtained. The calculation method of the model is introduced emphatically. The Matlab simulation result of this model is given. The model stability is analized. It is compared with other models. The result shows that the z-domain model is easier to calculate and uderstand, and more convenient to analize the stability of CP-PLL than those of the original models.关键词
