Some literature will state their T/H circuits are designed for 8-bit linearity. Which simulation they run and which spec they judge whether it is 8-bit linearity?

In my opinion, since T/H circuit input and output are all analog circuits. No INL/DNL spec can be put there. Are they measuring SDR and compare it with SNR requirement of certain No. of bits?

hi neoflash,
Yes you are right. They find the ENOB from Signal to Noise and Distortion ratio SINAD of the T/H circuit to determine its linearity.
