  Measuring Board Parasitics in High-Speed Analog Design
  PDF, 134 Kb, Datei veröffentlicht: 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

  Tuning in Amplifiers
  PDF, 44 Kb, Datei veröffentlicht: Oct 2, 2000
  Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket? Oscil

  Single-Supply Operation of Operational Amplifiers
  PDF, 77 Kb, Datei veröffentlicht: Oct 2, 2000
  Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.

  Current Feedback Amplifiers: Review, Stability Analysis, and Applications
  PDF, 53 Kb, Datei veröffentlicht: 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

  Noise Analysis for High Speed Op Amps (Rev. A)
  PDF, 256 Kb, Revision: A, Datei veröffentlicht: 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

  Wireline Data Transmission and Reception
  PDF, 191 Kb, Datei veröffentlicht: 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

  Stabilizing Current-Feedback Op Amps While Optimizing Circuit Performance
  PDF, 280 Kb, Datei veröffentlicht: 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

  Op Amp Performance Analysis
  PDF, 76 Kb, Datei veröffentlicht: Oct 2, 2000
  This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
