Abstract

A method for operating a time-interleaved analog-to-digital converter for converting an analog input to a digital output using a time-interleaved analog-to-digital converter, wherein the time-interleaved analog-to-digital converter comprises an array of M sub ADCs (ADC.sub.1, ADC.sub.2, . . . , ADC.sub.M), where M is an even integer, and each row of the array comprises one of the M sub ADCs. The method comprises the step of, for every sampling instant n, where n is an integer in a sequence of integers, converting the analog input by means of the sub ADC in row k(n) of the array, wherein 1.ltoreq.k(n).ltoreq.M. A value between 1 and M is assigned to k(n) for the first sample instant, and k(n+1) is selected such that a) k(n+1)>M/2 if k(n).ltoreq.M/2, otherwise k(n+1).ltoreq.M/2; b) M/2-1.ltoreq.|k(n+1)-k(n)|.ltoreq.M/2+1; and c) k(n+1)=k(m+1) if and only if n-m is an integer multiple of M. A time interleaved analog-to-digital converter operating in accordance with the method is also disclosed.
