zation noise only. With an input range equal to the full-
scale range of the ADC, calculate the ENOB as follows:
Total Harmonic Distortion
Total harmonic distortion (THD) is the ratio of the RMS
sum of the first five harmonics of the input signal to the
fundamental itself. This is expressed as:
where V1 is the fundamental amplitude, and V2 through
V5 are the amplitudes of the 2nd- through 5th-order
harmonics.
Spurious-Free Dynamic Range
Spurious-free dynamic range (SFDR) is the ratio of the
RMS amplitude of the fundamental (maximum signal
component) to the RMS value of the next largest distor-
tion component.
Full-Power Bandwidth
Full-power bandwidth is the frequency at which the input
signal amplitude attenuates by 3dB for a full-scale input.
Full-Linear Bandwidth
Full-linear bandwidth is the frequency at which the sig-
nal-to-noise plus distortion (SINAD) is equal to 56dB.
Intermodulation Distortion
Any device with nonlinearities creates distortion prod-
ucts when two sine waves at two different frequencies
(f1 and f2) are input into the device. Intermodulation
distortion (IMD) is the total power of the IM2 to IM5
intermodulation products to the Nyquist frequency rela-
tive to the total input power of the two input tones, f1
and f2. The individual input tone levels are at
-6dBFS.
