Abstract
A time interleaved analog-to-digital converter (TIADC) is provided. The TIADC converts an input signal into a digital output signal and includes N analog-to-digital converters (ADCs), a clock generation circuit, and a control circuit. The N ADCs receive the input signal and sample the input signal according to N sampling clocks to each generate a digital output code, N being an integer greater than or equal to 2. The clock generation circuit is configured to receive a working clock and a set of control values and to generate the N sampling clocks according to the set of control values and the working clock. The control circuit is configured to periodically generate the set of control values based on a pseudo random number and to output the digital output codes in turn as the digital output signal.
