Abstract
A time-interleaved analog-to-digital converter (ADC) uses M analog-to-digital converters to sample an analog input signal to produce digital outputs. The M ADCs, operating in a time-interleaved fashion, can increase the sampling speed several times compared to the sampling speed of just one ADC. The time-interleaved ADC can be programmed and reconfigured to trade one performance metric for another. For example, more time can be given to comparator to improve bit error rate or more time can be given to an amplifier for improved settling which improves SNR, SFDR etc. If the time-interleaved converters are randomized, then the amount of 'color' in the noise floor shape can also be traded for other performance metrics.
