Abstract
A hearing assistive device including an audio processing circuit with an analog-to-digital converter having an integrator integrating a voltage present in the summation point; a comparator comparing an output from the integrator with a reference voltage (V) and outputting a logical level in accordance with the comparison; a feedback loop coupling a feedback signal back to the summation point; and a reference voltage generation circuit being adapted to provide the reference voltage (V) being lower than a power supply voltage (V) and following the decay of the power supply voltage (V) with a predefined margin.
