Application Notes

  • The Current-Feedback Op Amp: A High-Speed Building Block
    PDF, 117 Kb, File published: Oct 2, 2000
    Although current-feedback amplifiers (CFAs) have been in use for quite some time, there is a reluctance to view them in the same light as voltage-feedback amplifiers (VFAs). For instance, the gain-bandwidth curve of VFAs has a parallel in a transimpedance-bandwidth curve for CFAs. This parameter can be used to determine the closed-loop behavior of the CFA in same way that GBW can for the VFA. Not
  • Noise Analysis for High Speed Op Amps (Rev. A)
    PDF, 256 Kb, Revision: A, File published: Jan 17, 2005
    As system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu
