In an FFT representation of converter data, the average noise floor (D) is a root-mean-square combination of all the bins within the FFT plot but excludes the input signal and signal harmonics. You ...

This FFT plot shows the test results of a SAR-ADC using coherent sampling with a data record (M) of 32,768 samples. The sampling frequency is locked to fS = 705.882 kHz, and the desired test input ...

Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...
