Electronic device and integrated circuit comprising a delta-sigma converter and method therefor

A method for converting an analog input signal to a digital output signal in a delta-sigma modulator incorporating a delta-sigma modulation loop and an analog to digital converter, the method comprising:

• periodically sampling an analog input signal with a plurality of comparators;
• and
• converting by the ADC the sampled analog input signal to a digital output signal representative of the analog input signal;
• determining a variation in the analog input signal;
• and
• shifting the digital output signal from the ADC to counteract an effect of the determined variation of the analog input signal and correspondingly shifting the analog input signal to the ADC via a feedback path.
