Patent attributes
Systems, methods, and circuitries for converting an analog voltage to a digital signal are provided. In one example a method to convert an analog voltage into a binary sequence that represents the voltage includes two modes. In the first mode, in each cycle, values for a next two or more of consecutive most significant bits (MSBs) in the sequence are determined using M comparators, wherein M is equal to or greater than 3. In a second mode, in each cycle, M redundant comparison results are determined using the M comparators. A value for the LSB is determined based on the M redundant values. At an end of conversion, the sequence of N bit values is generated based on the MSBs and the LSB.
