Data readout system having non-uniform ADC resolution and method thereof
Abstract:
A data readout system with non-uniform resolution has a pick up head for reading data stored in an optical disc and generating an analog signal, a reference voltage unit for producing a plurality of reference voltage levels, wherein voltage differences between two adjacent reference voltage levels are not all the same, a plurality of comparators for comparing the reference voltage levels with the analog signal and generating comparison results, and an encoder for encoding the comparison results into a digital signal.
