摘要： A time interleaving Analog-to-Digital Converter (ADC) comprises a plurality of ADCs; a timing generator that generates a dock signal for each of the plurality of ADCs such that edges of said clock signals trigger sampling of an input signal by the plurality of ADCs; and a timing adjustment circuit to receive and adjust the dock signals before the dock signals are received by the ADCs such that samplings of said input signal are spaced in time and occur at a rate of 1/N times a desired sampling rate; and a random number generator to pseudo randomly select which ADC samples the input signal; and a circuit for adjusting the bandwidth of the plurality of ADCs.
