...However, there are three drawbacks in the technique described in [6, 7]: 1) it requires two additional analogue blocks, namely a GN generator (GNG) and a programmablegain amplifier (PGA) to adjust the standard-deviation (σ) of the GNG; 2) since the output histogram has a Gaussian shape, an internal table containing the ideal mathematically-produced histogram has to be stored in a memory; 3) the σ of the GNG has to be calibrated with reasonable accuracy before the calibration of the ADC itself....
