摘要：

A novel adaptive compensation architecture for the frequency response mismatch of 2-channel Time-Interleaved ADC (TI-ADC) is proposed for developing high-yield self-adaptive systems. The proposed approach overcomes the existing methods in the sense that the TI-ADC mismatch identification can be performed without allocating a region where only the TI-ADC mismatch spurs are present. This is accomplished via mapping the TI-ADC problem into an I/Q mismatch problem which allows deploying complex statistical signal processing. As proof of the concept, the compensation architecture is demonstrated and tested on RF-sampling TI-ADC hardware data.
