Application Notes
- Using a Decompensated Operational Amplifier for Improved PerformancePDF, 161 Kb, File published: Mar 30, 2001
Decompensated operational amplifiers have improved noise, slew rate, harmonic distortion, etc., but required external compensation for stable operation. This report shows how to compensate such an amplifier and achieve the performance enchancement it provides in a unity-gain configuration.The THS4011 and THS4021 operational amplifiers are used to illustrate the superior performance mentioned a - Using a decompensated op amp for improved performancePDF, 352 Kb, File published: Mar 11, 2005
- 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
