Signal Chain Basics #160: Making sense of coherent and noncoherent sampling in data-converter testing

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

Tips and Tricks for Addressing Fixed-Frequency Spurs in ADC Signal Chains

Today’s successive-approximation-register (SAR) analog-to-digital converters (ADCs) and sigma-delta ADCs are known for their high resolution and low noise. Nevertheless, achieving signal-to-noise (SNR ...

Using input-referred noise to improve analog-to-digital converter resolution

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...
