Application Notes
- Transimpedance Considerations for High-Speed Operational AmplifiersPDF, 193 Kb, File published: Nov 22, 2009
Designing high-resolution detection circuits using photodiodes presents considerable challenges because bandwidth, gain, and input-referred noise are coupled together. This application note reviews the basic issues of transimpedance design, provides a set of detailed design equations, explains those equations, and develops an approach to easily compare potential solutions. - Transimpedance Amplifiers (TIA): Choosing the Best Amplifier for the job (Rev. A)PDF, 153 Kb, Revision: A, File published: May 16, 2017
This application note is intended as a guide for the designer looking to amplify the small signal from a photodiode or avalanche diode so that it would be large enough for further processing (e.g. data acquisition) or to trigger some other event in a system. The challenge in doing so, as always, is to not degrade the signal such that it becomes indistinguishable from random noi - 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
