提出并实验证明了光子模数转换中的自适应阈值方案。采用差分检测技术代替单端电子比较器来减少阈值误差引起的量化噪声。该方案的主要优点是消除了阈值水平的动态设置以及对共模噪声的更好的容忍度。
An adaptive thresholding scheme in photonic analog-to-digital conversion is proposed and experimentally demonstrated. Instead of a single-ended electronic comparator, differential detection technology is used to reduce the quantization noise induced by thresholding error. The main advantages of this scheme are the elimination of the dynamic setting of thresholding level and better tolerance to common-mode noise.
