- 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
