The Stability Factor Setting Value Analysis for PLL*
摘要
Abstract
The parameter equation of influencing the systematical stability was established by studying the phase transfer model, the phase transfer function and the error of transfer function of the typical higher-order charge pump phase-locked loop system and using the real root discriminant methods of unitary quadratic function inequality equation. The high-order phase-locked loop stability factor( second-order filter ration m and system attenuation factor ξ) were deduced by the generating ways. And the parameter value ranges( look-up table)were calculated in ensuring the margin of the loop phase under the conditions more than 60°. It has certain directive significance for the design of similar loop. The stability design of similar loop can be referred.关键词
