应用须知
- The Current-Feedback Op Amp: A High-Speed Building BlockPDF, 117 Kb, 档案已发布: 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, 修订版: A, 档案已发布: 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
