Abstract:
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. At least one of the first and second reference signals is adjusted. A second comparison result is generated if the analog signal reaches an adjusted one of the first and second reference signals within a predetermined interval, and a second portion of the digital signal is generated from the second comparison result.
