| 摘要: |
| 时间交替采样技术对通道失配误差十分敏感，而基于混合滤波器组的采样技术降低了对通道失配误差的敏感，但前端模拟分析滤波器的稳定性难于设计限制了其工程应用。结合时间交替和混合滤波器组采样技术，提出了一种易于工程实现的基于混合滤波器组的时间交替采样技术。仿真结果表明，该技术能显著提高采样系统的精度。 |

| Time-interleaved Sampling Technology Based on Hybrid Filter Banks |
|
| () |
| Abstract: |
| Time-interleaved sampling technology is very sensitive to the channel mismatch errors.The sampling technology based on hybrid filter banks can reduce the sensitivity to the channel mismatch errors,the engineering application is limited because the stability of the front analog analysis filter banks is very difficult to design.In this paper,a time-interleaved sampling method based on hybrid filter banks is proposed which can be realized easily on engineering application.Simulation results demonstrate this method can increase the system sampling resolution obviously. |
| Key words: ADC,hybrid filter banks,time-interleaved sampling,channel mismatch error |
