Abstract

An analog-digital converter includes a first analog-digital conversion unit configured to, during a first analog-digital conversion operation, sequentially charge each of n first differential node pairs, in response to a respective one of a differential sampling signal pair and first to (n−1)differential signal pairs among n differential signal pairs, in response to each of the n first differential node pairs being sequentially charged, sequentially generate each of n first differential data pairs, and sequentially generate each of n upper differential data pairs to be used as n-bit upper digital data, in response to a respective one of the sequentially-generated n first differential data pairs. The first analog-digital conversion unit is further configured to, during a second analog-digital conversion operation, simultaneously discharge each of the n first differential node pairs, in response to a ndifferential signal pair among the n differential signal pairs.
