负电阻取消运算放大器负载

：取消负载允许运算放大器的能力高输出电流，同时维持所有其他高精度规格，例如，获得了很高的开放环，低偏置的电压和电流、低偏移电压和电流的偏移量的噪音，低失真。Maxim>AppNotes>AMPLIFIERANDCOMPARATORCIRCUITSKeywords:negativeresistance,opamp,operationalamplifier,loadcanceling,open-loopgain,lowoffsetJan31,2003voltage,offsetcurrent,lowoffset-voltage,offset-currentnoise,lowdistortion,opampAPPLICATIONNOTE1868NegativeResistorCancelsOpAmpLoadAbstract:Cancelingtheloadallowstheopampthecapabilityforhighoutputcurrentwhilemaintainingalltheotherhigh-accuracyspecificationssuchasveryhighopen-loopgain,lowoffsetvoltageandcurrent,lowoffset-voltageandoffset-currentnoise,andlowdistortion.Accurateopampsareoftencharacterizedashavingveryhighopen-loopgain,lowoffsetvoltageandcurrent,lowoffset-voltageandoffset-currentnoise,andlowdistortion.Conspicuouslyabsen
