Abstract
An integrated circuit comprises a delta-sigma modulator incorporating a delta-sigma modulation loop having an analog-to-digital converter in a forward path and a digital-to-analog converter in a feedback path such that the ADC is arranged to receive samples of an analog input signal. The ADC is operably coupled to auto-ranging logic arranged to shift a digital output signal from the ADC representative of the analog input signal to counteract an effect of an input variation of the analog input signal. In this manner, the application of auto-ranging logic with a self-recovery technique supports a reduction of the number of comparators required in a multi-bit delta-sigma ADC.
