Abstract
A non-ideal Hadamard modulator in the front-end of ΠΔΣ ADC can be modelled as an ideal Hadamard modulator with gain error in parallel with an offset error. The effects of non-ideal Hadamard modulators can be partially removed by using chopper stabilisation and adaptive channel gain equalisation
