The Current-Feedback Op Amp: A High-Speed Building Block
PDF, 117 Kb, Datei veröffentlicht: 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, Datei veröffentlicht: 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
