Abstract
We build a model of channel response for time-interleaved photonic analog-to-digital converters (TIPADCs) including interchannel and intrachannel crosstalks. The characteristic of the channel magnitude responses of TIPADCs in the cases with and without mismatch are analyzed under different backend bandwidths. When a backend bandwidth is less than half of the overall sampling rate, interchannel crosstalk will cause a periodical variation on the corresponding channel magnitude response in mismatch-free TIPADCs, with the period being the overall sampling rate. The periodicity caused by interchannel crosstalk will be disrupted by time mismatch in TIPADCs. The theoretical analyses are verified by the simulation results of 2- and 4-channel TIPADCs and experimental measurements of a 2-channel TIPADC system.
