摘要：一些开关电容滤波器时钟（超临界流体）与外部元件除了自同步，但大多数应用程序使用一个CMOS电平的时钟信号设置SCF的角频率。本应用笔记讨论产生证监会更常见的方法。Maxim>DesignSupport>TechnicalDocuments>Tutorials>FilterCircuits(Analog)>APP724Maxim>DesignSupport>TechnicalDocuments>Tutorials>SignalGenerationCircuits>APP724Keywords:switchedcapacitor,filter,clocks,filters,analog,signalgeneration,scfNov19,2001TUTORIAL724GeneratingSwitched-Capacitor-FilterClocksNov19,2001Abstract:Someswitched-capacitor-filterclocks(SCFs)areself-clockingwiththeadditionofexternalcomponents,butmostapplicationsuseaCMOS-levelclocksignaltosettheSCF'scornerfrequency.ThisapplicationnotediscussesthemorecommonmethodsforgeneratingaSFC.Recentadvancesinsemiconductor……
