- Demystifying the Operational Transconductance Amplifier (Rev. A)PDF, 259 Kb, Revisión: A, Archivo publicado: abr 16, 2013
Operational transconductance amplifiers (OTAs) are often among the least understood analog components. However, these devices serve a very useful function that is being implemented on a regular basis in many integrated circuits as an element for more advanced purposes; the current feedback amplifier is among the most prominent example. The purpose of this application report is to show how this bui - Noise Analysis for High Speed Op Amps (Rev. A)PDF, 256 Kb, Revisión: A, Archivo publicado: enero 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
