| 摘 要： | 并行时间交替采样是提高采样率的一种有效方法,但并行通道间的失配将使拼接后的信号成为非均匀采样,严重降低了整个系统的性能。该文在分析并行时间交替采样信号频谱的基础上,给出了时间误差的测量方法,并采用FARROW结构的全通滤波器实现时间误差校正。仿真结果表明该方法能有效提高信号频谱质量,实现了对非均匀采样信号的时间误差校正。

| Abstract: | The parallel time-interleaved ADC is an effective method to improve sample-rate. However, channel mismatches lead to nonuniform sampling and degrades the performance of the whole ADC system. After analyzing the signal spectrums, this paper proposed a method to measure and verify the time-skew errors. The experiment results show that the method can calibrate the spectrums effectively. |
