TLV9151: rectification effect

Hi Eli,

this may interest you:

Characterization of the rectification behaviour of in-amps and es.pdf

"Rectification" takes place when the input signal is so high-frequency that the OPAmp cannot respond in time. Then the input signal becomes demodulated across non-linearities of input stage and unexplainable noise and weird DC voltages can be seen at the output of OPAmp.

See how a DC offset develops across a parabolic transfer characteristic:

thanks much

the only matter to me is the DC offset at the output . can you recommend test setup for that only? 

do you know what op amps rectification effect is added to their datasheets?

appreciate your help
