| Sumario: | The advancement of optical communications, and growing market demand, have favored an increase in transmission speeds for large volumes of data. Although the optical fiber is capable of handling this information without major inconveniences, the electrical stage has some limitations.
The conversion from analog domain to the digital domain and vice versa, requires conversion devices ADC and DAC capable of processing these volumes of information and with high-speed conversion rates. The evolution of converters, thanks to parallel architectures, like timing interleaved, has obtained substantial improvements in terms of conversion speed, however, no improvements in bandwidth are observed, since, to promote the increase in speed, the parallelism had to be increased.
Against this background, the use of the FI technique is proposed, the application of which would be possible in both transmitting and receiving devices FI-ADC and FI-DAC. This pre-processing in receivers (and post-processing in transceivers), makes it possible to increase the general system bandwidth, utilizing converters with less BW.
This work presents the simulation of a proof platform for the application of the FI-ADC technique, and the performance results obtained from it. |
