    Design for a Wideband Differential Transimpedance DAC Output (Rev. A)
    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

    Noise Analysis for High Speed Op Amps (Rev. A)
    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
