ABSTRACT:
An analog-to-digital converter is adapted to operate with input signals having relatively large signal level variations, with the mean level of such signal centered at the midpoint in the operating range of the converter. The converter includes a series of cascade encoding stages, each one providing a digital output signal and a residue output signal, the latter such signal being passed as the input to the succeeding encoding stage. Each one of the cascaded encoding stages includes means for producing an analog residue output signal having a linear relationship to the analog signal applied to each such stage in the middle region of the operating range of each such stage. Such means includes a pair of amplifiers having diode-resistor feedback arrangements.
