| Abstract: | A time-interweaved sampling scheme for optical A/D conversion is proposed, and 16×2.5 GHz sampling rate to microwave signal was realized. The sampling errors are analysed and the methods to improve sampling precision are discussed. The experiment result was revised and SNR is about 29 dB. |
