| 摘 要： | 在一些数据采集领域,需要对信号进行高速率采样,但是单芯片难于满足要求。本设计采用三路ADC交叉采样方式,结合采样时钟等相位差设计、采样误差校正、高速数据处理措施,通过对被采样信号和还原信号的对比,验证了本设计的正确性。本设计最高采样速率可达195MHz。

| Abstract: | In some areas of data acquisition,it is necessary to sample the signal at a high rate,but a single chip is difficult to meet the requirements.This design adopts three-channel ADC cross-sampling mode,combined with sampling clock phase difference design,sampling error correction,high-speed data processing measures,through the comparison of the sampled signal and the restored signal,the correctness of the design is verified.The highest sampling rate of this design can reach 195MHz. |
