ABSTRACT:
An analog-digital converter supplying a digital output signal in natural or reflected binary code, having an input stage, n consecutive conversion stages comprising two parallel channels of identical structure, in each of which there are two current paths in accordance with the result of a comparison of currents effected in the preceding stage and an output stage to which the switched currents proceed. In the complete converter there are 2.sup.n current paths corresponding to 2.sup.n quantization levels. Conversion is effected by means of a number of stages as small as the number n of bits of the desired digital signal. This converter is simple, fast, asynchronous, has a lower power consumption and its symmetry provides excellent automatic temperature compensation.
