  • Analog-digital encoding circuit with automatic compensation for the zero offset
    Patent number: 5424738
    Abstract: This analog-digital coding circuit comprises, in parallel on an analog-digital converter, a crossover detector. This crossover detector operates on the input analog signal of the converter and, by means of a delay circuit, taking account of the conversion time of the converter, commands the recording of values in a digital register placed at output of the converter. A digital subtractor, placed at output of the coding circuit, makes a systematic deduction, from the digital values delivered by the converter, of that value which is memorized in the digital register and corresponds to the offset voltage of the converter.
