DEFINITION OF SPECIFICATIONS

Total Harmonic Distortion (THD)

THD is the ratio of the power of the fundamental (PS) to

the power of the first eight harmonics (PD).

THD + 10Log10

THD is typically given in units of dBc (dB to carrier).

Spurious-Free Dynamic Range (SFDR)

The ratio of the power of the fundamental to the highest

other spectral component (either spur or harmonic).

SFDR is typically given in units of dBc (dB to carrier).

Two-Tone Intermodulation Distortion

IMD3 is the ratio of the power of the fundamental (at

frequencies f1 and f2) to the power of the worst spectral

component at either frequency 2f1−f2 or 2f2−f1. IMD3 is

either given in units of dBc (dB to carrier) when the

absolute power of the fundamental is used as the

reference, or dBFS (dB to full scale) when the power of

the fundamental is extrapolated to the converter’s

full-scale range.
