Application Notes
- Transimpedance Considerations for High-Speed Operational AmplifiersPDF, 193 Кб, Файл опубликован: 22 ноя 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 Кб, Версия: A, Файл опубликован: 16 май 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 - Using a decompensated op amp for improved performancePDF, 352 Кб, Файл опубликован: 11 мар 2005
- Voltage Feedback vs. Current Feedback Op AmpsPDF, 93 Кб, Файл опубликован: 30 ноя 1998
This application report contrasts and compares the characteristics and capabilities of voltage and current feedback operational amplifiers. The report also points out the many similarities between the two versions. - Designing for low distortion with high-speed op ampsPDF, 277 Кб, Файл опубликован: 2 мар 2005
- Measuring Board Parasitics in High-Speed Analog DesignPDF, 134 Кб, Файл опубликован: 7 июл 2003
Successful circuit designs using high-speed amplifiers can depend upon understanding and identifying parasitic PCB components. Simulating a design while including PCB parasitics can protect against unpleasant production surprises. This application report discusses an easy method for measuring parasitic components in a prototype or final PC board design by using a standard oscilloscope and low freq - Noise Analysis for High Speed Op Amps (Rev. A)PDF, 256 Кб, Версия: A, Файл опубликован: 17 янв 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
