A photonic analog-to-digital converter exploiting a sample time-interleaving approach is presented, showing more than 7 effective bits for input signals up to 40GHz and bandwidth up to 200MHz. The effective 1-to-4 optical sample parallelization scheme does not contaminate the low sampling jitter with limited crosstalk. A real-time digital post-processing is also added to increase the ADC linearity and to minimize the spurious tones induced by the digital data interleaving. The results show that… CONTINUE READING
