Linearity of MOS transistor_the meaning

[akkafrawy]

Hi, can anyone tell me what does " a 10 bit linearity can be extracted from 90nm CMOS transistor" mean? how is it related to the Ids-Vgs of such a transistor? Has it a relation to the dynamic range?...any info, thx

This is a very vague term to be used for a single CMOS transistor. Usually ENOB is used in ADCs to express their DR equivalence in bits. Can you share its reference ?

Unfortunately, I don't have ref., but i heard it a lot in many lectures

it might be dealing with missmatch of MOSFETs (say better 0.1%), providing 10-bit linearity e.g. in current steering DAC

Or it can be that a MOS transistor with a certain THD (Id vs Vg) corresponds to an equivalent SDR (signal to distortion) which results in 10bit ENOB.

A bit of context would be nice.
