Transimpedance Considerations for High-Speed Operational Amplifiers
PDF, 193 Kb, 档案已发布: 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.

ADS5500, OPA695: PC Board Layout for Low Distortion High-Speed ADC Drivers
PDF, 273 Kb, 档案已发布: Apr 22, 2004
Once an analog-to-digital converter (ADC) and a driver/interface have been selected for a given application, the next step to achieving excellent performance is laying out the printed circuit board (PCB) that will support the application. This application report describes several techniques for optimizing a high-speed, 14-bit performance, differential driver PCB layout using a wideband operation

Measuring Board Parasitics in High-Speed Analog Design
PDF, 134 Kb, 档案已发布: Jul 7, 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 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
