  Design for a Wideband Differential Transimpedance DAC Output (Rev. A)
  PDF, 438 Kb, Revision: A, File published: Oct 17, 2016
  High-speed digital-to-analog converters commonly offer a complementary current output signal. Most output interface implementations use either a resistive load and/or a transformer to convert this current source signal to a voltage. Where a dc-coupled interface is required, a carefully designed differential transimpedance stage can offer an attractive alternative. Design considerations and options

  Fully-Differential Amplifiers (Rev. E)
  PDF, 867 Kb, Revision: E, File published: Sep 19, 2016
  Differential signaling has been commonly used in audio, data transmission, and telephone systems for many years because of its inherent resistance to external noise sources. Today, differential signaling is becoming popular in high-speed data acquisition, where the ADC’s inputs are differential and a differential amplifier is needed to properly drive them.Two other advantages of di

  Driving High-Speed ADCs: Circuit Topologies and System-Level Parameters (Rev. A)
  PDF, 327 Kb, Revision: A, File published: Sep 10, 2010
  This application report discusses the performance-related aspects of passive and active interfaces at the analog input of high-speed pipeline analog-to-digital converters (ADCs). The report simplifies the many possibilities into two main categories: passive and active interface circuits. The first section of the report gives an overview of equivalent models of buffered and unbuffered ADC input cir

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