摘要:
为了满足现代数字信号处理(Digital signal processing,DSP)技术对高速、高精度模数转换的要求,提出采用光电混合的方法解决电子模数转换器存在载流子迁移速率物理极限的问题。提出了一种采用时域展宽光辅助电采样量化方法实现20 GHz高速采样的实施方案,对方案中超短光脉冲源、线性啁啾光载波产生、光学时间拉伸、多通道数据重组等关键技术进行了分析,最后,采用采样速率5 GSa/s,模拟带宽3.2 GHz、量化精度10 b的电子模数转换器(EVQ190)完成了对一个5通道的微波信号时间拉伸系统的数值仿真。通过多通道数据融合和校正方法得到了仿真结果。仿真结果表明:该设计能达到7位以上的有效位。
Abstract:
In order to meet the requirements of the modern digital signal processing(DSP)technology for high-speed and high-precision modulus conversion,a method of the photoelectric hybrid is proposed to solve the problem of the physical limit of carrier migration rate in electronic analog-digital converter(ADC). In this paper,an implementation scheme of realizing 20 GHz high-speed sampling by using time-domain broadening optical assisted electrical sampling quantization method is proposed. The key technologies such as ultrashort optical pulse source,linear chirped optical carrier generation,optical time stretching and multi-channel data recombination are analyzed. An electronic ADC(EVQ190)with sampling rate of 5 GSa/s,simulating bandwidth of 3.2 GHz and quantization accuracy of 10 bits is used for the numerical simulation of a 5-channel time-stretching system of microwave signal is completed. Simulation results are obtained by the multi-channel data fusion and the correction method. The results show that the design can achieve over seven significant bits.
