Time interleaved analog-to-digital converter

A time interleaved analog-to-digital converter (TIADC) for converting an input signal into a digital output signal, comprising:

• N analog-to-digital converters (ADCs), each of which receives the input signal and samples the input signal according to one of N sampling clocks to generate a digital output code, N being an integer greater than or equal to two;
• a clock generation circuit coupled to the N ADCs, for receiving a working clock and a set of control values, and generating the N sampling clocks according to the set of control values and the working clock;
• and
• a control circuit coupled to the N ADCs and the clock generation circuit, for periodically generating the set of control values, and outputting the digital output codes in turn as the digital output signal;
• wherein two consecutive sets of control values are not identical.
