Analog Front-End
Power-supply rejection is defined as the shift in offset
and gain error when the power supply is changed ±5%.
A small -20dBFS analog input signal is applied to an
ADC in so that the signal’s slew rate does not limit the
ADC’s performance. The input frequency is then swept
up to the point where the amplitude of the digitized
conversion result has decreased by 3dB. Note that the
T/H performance is usually the limiting factor for the
small-signal input bandwidth.
A large -0.5dBFS analog input signal is applied to an
ADC, and the input frequency is swept up to the point
where the amplitude of the digitized conversion result
has decreased by 3dB. This point is defined as the full-
power bandwidth frequency.

THD is the ratio of the RMS sum of the output harmonics
up to the Nyquist frequency divided by the fundamental:

Spurious-free dynamic range (SFDR) is the ratio of RMS
amplitude of the fundamental (maximum signal compo-
nent) to the RMS value of the next-largest distortion
component up to the Nyquist frequency excluding DC.
