Wideband Complementary Current Output DAC Single-Ended Interface
PDF, 597 Kb, Datei veröffentlicht: Jun 21, 2005
High-speed digital-to-analog converters (DACs) most often use a transformer-coupled output stage. In applications where this configuration is not practical, a single op ampdifferential to single-ended stage has often been used. This application note steps through the exact design equations required to achieve gain matching from each output as well as a matched input impedance to each of the DA

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
