Hello,
Due to my limited knowledge, I see most of the high resolution delta-sigma modulator is fully differential one. In that case the 2nd harmonic distortion is cancelled and with the feedback loop the 3rd harmonic is attenuated. Now if we consider the normal audio channel (the transducer is often single-ended), so if I use a single-ended continuous-time delta-sigma ADC, do I have the problem of the SNDR due to the 2nd harmonic distortion? For example, if I want to achieve 16 bit resolution, is it possible? Would anybody recommend me some references? Thank you.
