a time interleaved analog - to - digital converter includes a plurality of analog - to - digital subconverters which are monolithically integrated in an array on a semiconductor chip and are sequentially activated into sampling and conversion operation in the time interleaved fashion for converting a received analog signal into a digital form . if an analog - to - digital subconverter in the i - th row of the j - th column of the array is activated at one sampling time in the sequential activation , an analog - to - digital subconverter in the k - th row of the l - th column is subsequently activated , where i , k , j and l bear the relations expressed by : i - 2 ≦ k ≦ i + 2 and j - 2 ≦ l ≦ j + 2 . the sequential activation of the analog - to - digital subconverter array assures that the analog - to - digital subconverters disposed in physical proximity to one another are successively activated , thus greatly improving the differential linearity of the analog - to - digital converter characteristics .
