Zusammenfassung:	A method is provided. An analog signal is received. The analog input signal is compared to first and second reference signals to generate a first comparison result, and the first comparison result and a first time stamp corresponding to the first comparison result are registered. A first portion of a digital signal is generated from the first comparison result. If the comparison result remains substantially the same for a predetermined interval, an ADC is enabled to generate a second comparison result at a sampling instant. A second time stamp that corresponds to the sampling instant is generated. The second comparison result and a second time stamp corresponding to the first comparison result are registered, and a second portion of the digital signal is generated from the second comparison result.
