中文摘要：

通过对并行时间交替采样（Time-interleaved ADC,TIADC）理论和采样时间失配误差的研究,提出一种带时间补偿的自适应TIADC数据采集方案.方案首先产生具有等相位差的采样时钟,通过自适应电路估计时间失配误差;然后利用Farrow结构的分数延时滤波器对多通道采集数据进行校正,并交叉合并,得到高速TIADC数据;最后通过FPGA实验验证,证明自适应TIADC数据采集不仅可以提高采样率,而且能有效校正时间失配误差,保证数据采集的准确性.

英文摘要：

A design of adaptive TIADC data acquisition with time compensation is pro- posed by the study of parallel time-interleaved ADC （TIADC） theory and sampling time mismatch error. Firstly, sampling clocks with equal phase difference are generated from clock management, estimated time mismatch deviation by the adaptive circuit; then, the multi-channel data acquisition is corrected by Farrow structure＇ s fractional delay filter, and cross merged to obtain High-speed TIADC acquisition data;Finaly, the results of FPGA experimental verification show that adaptive TIADC acquisition system can not only increase the sampling rate, but also correct the time mismatch error effectively, thus ensure the accuracy of TIADC data collection.
