Various parallel ADC structures with mixers (such as DBI-ADC, ATI-ADC) are attractive structures for broadband high-speed data acquisition systems. However, these structures have inherent disadvantages: the phase difference between subbands in the vicinity of overlapping bands of adjacent subbands causes the system frequency response to deteriorate significantly. The original correction method relies on high-performance circuits and components or correction algorithms that consume a lot of digital resources. This paper proposes a new method of phase difference correction for overlapping frequency bands and proves its effectiveness through experimental results. This method uses the structural characteristics of the acquisition system itself, without additional resources, and ensures that the phase difference does not affect the system SNR.
