Abstract: A system includes a first circuit board including one or more first computing circuits. The system further includes an interconnect device coupled with the one or more first computing circuits. The interconnect device includes a linear re-driver configured to receive an electrical input signal from at least one of the one or more first computing circuits. The linear re-driver is further configured to boost the electrical input signal to form a boosted electrical signal. The linear re-driver is further configured to output the boosted electrical signal. The interconnect device is configured to provide the boosted electrical signal to one or more second computing circuits of a second circuit board over one or more wired connections. The boost to the electrical input signal compensates for a known loss associated with the one or more wired connections.

Abstract: Embodiments are disclosed for tuning a continuous time linear equalizer embedded in a receiver of a communication system. An example method includes receiving an N-point estimation of a channel pulse response associated with an input signal. The method further includes calculating an estimated power spectral density for one or more desired frequency bands. The method further includes updating one or more parameters of a continuous time linear equalizer to adjust one or more power densities of the one or more desired frequency bands based on the one or more estimated power spectral densities calculated. The method further includes calculating, for each desired frequency band, an estimated power spectral density after updating the one or more parameters of the continuous time linear equalizer to adjust the one or more power densities of the one or more desired frequency bands.

Abstract: Embodiments are disclosed for channel estimation in a receiver of a communication system. An example method includes receiving, via a receiver of a communication system, an input signal. The example method further includes using a first event indicator embedded in an analog circuit of the receiver to slice the input signal to generate a sliced input signal and applying an offset to the input signal to generate an offsetted signal. The example method further includes using a second event indicator embedded in the analog circuit to slice the offsetted signal to generate a sliced offsetted signal. The example method further includes applying a first predefined delay to the sliced input signal and applying a second predefined delay to the sliced offsetted signal. The example method further includes generating a conditional ones signal based on the sliced input signal and the sliced offsetted signal and using the conditional ones signal to calibrate an equalizer embedded in the receiver.
