A Self-Adaptive Frequency Response Compensation Method for a TIADC System

الملخص EN

Time interleaving is one of the most efficient techniques employed in high-speed sampling systems.

However, the frequency response mismatch among different channels will create distortion tones that degrade the system performance.

In this paper, a self-adaptive frequency response mismatch compensation method is presented, where the design of compensation filter is optimized with a self-adapting strategy.

This digital postprocessing technique realizes the compensation of frequency response effectively and also the increase of the digital bandwidth of the acquisition system.

MATLAB-based simulation and an actual two-channel acquisition system test verify the effectiveness of the algorithm.
