  Current Feedback Amplifiers: Review, Stability Analysis, and Applications
  PDF, 53 Кб, Файл опубликован: 20 ноя 2000
  The majority of op amp circuits are closed-loop feedback systems that implement classical control theory analysis. Analog designers are comfortable with Voltage FeedBack (VFB) op amps in a closed-loop system and are familiar with the ideal op amp approximations feedback permit. This application bulletin will demonstrate how CFB op amps can be analyzed in a similar fashion. Once the closed-loop sim

  Stabilizing Current-Feedback Op Amps While Optimizing Circuit Performance
  PDF, 280 Кб, Файл опубликован: 28 апр 2004
  Optimizing a circuit design with a current-feedback (CFB) op amp is a relatively straightforward task, once one understands how CFB op amps achieve stability. This application note explains a 2nd-order CFB model so that any designer can better understand the flexibility of the CFB op amp. This report also discusses stability analysis, the effects of parasitic components due to PCBs, optimization

  RLC Filter Design for ADC Interface Applications (Rev. A)
  PDF, 299 Кб, Версия: A, Файл опубликован: 13 май 2015
  As high performance Analog-to-Digital Converters (ADCs) continue to improve in their performance, the last stage interface from the final amplifier into the converter inputs becomes a critical element in the system design if the full converter dynamic range is desired. This application note describes the performance and design equations for a simple passive 2nd-order filter used successfully in AD

  ADS5500, OPA695: PC Board Layout for Low Distortion High-Speed ADC Drivers
  PDF, 273 Кб, Файл опубликован: 22 апр 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 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
