Bipolarer A/D-Wandler mit automatischer Offsetkompensation |
摘要 |
An automatic offset compensating bipolar A/D converter circuit includes an A/D converter and a feedback circuit, which automatically compensates offset error between a specific level of input having analog voltage and a specific output code of output digital value corresponding to that input analog voltage. The A/D converter can convert the input analog voltage, which includes residual noises more than 1 LSB, into an output digital value. The feedback circuit can add a compensation voltage to the input analog voltage so as to equalize the posibilities of occurrence of codes which are more than and less than a specific output code of an output digital value to each other in accordance with an output digital value. |
