Principle and realization method for one kind of voltage controlled tracking filter 压控跟踪滤波器原理与实现方法
This paper suggests that in the analysis of the complex phase locked loops all the components of a phase locked loop be treated, equivalently as a phase discriminator except the voltage controlled oscillator and the loop filter. 本文建议在分析复杂锁相环时,把压控振荡器(VCO)和环路滤波器之外的所有其它部件等效地看成是一个鉴相器。
Using the proposed control method, the control system need not to be decoupled and the system voltage fluctuation can be well controlled by only a d-q transformation module and a low-pass filter, so this method is simple and the control strategy possesses good robustness. 该控制方法不需要对控制系统解耦,只需要1个d-q变换模块和1个低通滤波器即可较好地抑制系统电压波动,控制方法简单、鲁棒性高。
The PLL type frequency synthesizer always contain voltage controlled oscillator, frequency divider, phase frequency detector, charge pump, and loop filter. 锁相环型频率综合器主要由压控振荡器,分频器,鉴频鉴相器,电荷泵以及环路滤波器等模块组成。
