A analog-to-digital converter includes: an analog signal input, a reference voltage source, a portion for the combined processing of the analog signal and reference voltage, and a coding portion for supplying a digital output signal which is a function of the results of this processing. The processing portion includes at least one level of processing operators suitable for carrying out a non-linear calculation from their inputs; the coding portion include one level of output operators, each having as many inputs as there are outputs in the last level of operators in the processing portion. The transfer functions of the processing operators and output operators are chosen so as to allow an optimum analog-to-digital conversion over a given range of input signals.
