摘要：随着集成电路（Ic）加快速度，上升/下降时代的大多数脉冲和函数生成器（典型5ns）成为测量低于20ns的时间间隔不足。你可以克服这种限制与模拟交换机或先进的CMOS逻辑门，创建数字边速度更快。开通/这些开关关断时间产生非常快速上升/下降时间。单刀双掷（SPDT）开关，可以创建脉冲的高和低层次的是可编程。Maxim>AppNotes>SIGNALGENERATIONCIRCUITSSWITCHESANDMULTIPLEXERSKeywords:pulsegenerator,CMOSswitches,CMOSlogicgates,SPDTswitch,analogswitches,highspeedpulseJan31,2003generator,MAX4644,fastrise/falltimes,pull-up/pulldowndriver,SPDTanalogswitch,outputdriver,functiongenerators,fastdigitaledgeAPPLICATIONNOTE1866High-SpeedPulseGeneratorHasProgrammableLevelsAbstract:Asintegratedcircuits(ICs)speedup,therise/falltimesofmostpulseandfunctiongenerators(5nstypical)becomeinadequateformeasuringtimeintervalsbelow20ns.YoucanovercomethislimitationwithanalogswitchesoradvancedCMOSlogicgates,whichcreatefasterdigitaledges.Theturn-on/turn-offtimesfortheseswitchesproduceveryfastrise/fall……
