Method and circuit for encoding and transmitting numerical values from an analog-to-digital conversion process

摘要

An analog-to-digital converter system and methodology comprising an analog-to-digital converter circuit configured to provide sequentially a plurality of codes designating a numerical value in a first number system. The analog-to-digital converter system further comprising an encoder interface circuit configured to receive the plurality of codes and to derive a redundant digital representation. A portion of the redundant digital representation is transmitted during the conversion period. The encoder interface circuit may be configured to use a numerical successive-approximation algorithm to derive the redundant digital representation. A substantial portion of the redundant digital representation may be transmitted via a serial interface during the conversion period to reduce an overall latency.
