sfdr receiver

Spurious Free Dynamic Range (SFDR) is the usable range of an ADC device before these spurious signals distort or interfere with the signals of interest.
 

what is sfdr

... measured as the difference between the wanted signal to the first spur levels.

what is sfdrl

To be more precise: it is the difference between the power of the signal and the one at which the spurious signals and noise are the same.

Complementary comment: The SFDR is also used for receiver design in general. :)

Re: What is SFDR?

This paper offers quite clear explanation.

As belowing paper told me, put a SHA in front of AD convert can improve the sensitivity.
Does anyone have relative experience?

Re: What is SFDR?

SFDR is:
The difference between the lagrest input signal (That makes the third
order intercept is equal to the noise floor of your system) and your
systems noise floor.
