  A Numerical Solution to an Analog Problem
  PDF, 210 Kb, 档案已发布: Apr 25, 2010
  In order to derive a solution for an analog circuit problem, it is often useful to develop a model. This approach is generally accepted as developing an analytical model. However, finding the analytical solution is not always practical or possible as a result of higher-degree polynomials that require further resolution, or because of the time needed to develop the solution completely. In these sit

  Current Feedback Amplifiers: Review, Stability Analysis, and Applications
  PDF, 53 Kb, 档案已发布: Nov 20, 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 Kb, 档案已发布: Apr 28, 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

  Wireline Data Transmission and Reception
  PDF, 191 Kb, 档案已发布: Jan 27, 2010
  Many types of wires are widely used to transmit data. Specifically, Category 3 and Category 5 (Cat3 and Cat5e, respectively)—also known as unshielded twisted pair or UTP lines—are now recommended for new telephone installations. Coaxial (coax) cables are used to distribute cable television (CATV) signals throughout a home. #12 and #14 American wire gauge (AWG) electric power distribution wire is a

  RLC Filter Design for ADC Interface Applications (Rev. A)
  PDF, 299 Kb, 修订版: A, 档案已发布: May 13, 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

  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
