Samsung patents signal receiver that adjusts data bits to fix noise
This filing describes a receiver for electronic devices that cleans up incoming signals using a specific type of error correction called feed-forward equalization. It includes a circuit that adjusts the digital values of the signal's parts, known as taps, using control signals to improve accuracy.
In the filing’s own words
An example signal receiver according to the present disclosure comprises an analog-to-digital conversion circuit configured to perform digital sampling on a amplified signal to generate a plurality of analog-to-digital conversion signals, a feed forward equalization circuit including a plurality of feed forward equalizers configured to perform feed forward equalization on the plurality of analog-to-digital conversion signals to generate feed forward equalization signals, and a masking bit control circuit configured to generate a first masking bit control signal associated with the feed forward equalization, where a first feed forward equalizer of the plurality of feed-forward equalizers is configured to generate a plurality first tap output signals, and adjust a digital value of each of the plurality of first tap output signals to generate the first masking signals based on the first masking bit control signals.
What exactly they claim (claim 1)
1. A signal receiver comprising: an analog front-end circuit configured to perform an amplification operation on a signal to generate an amplified signal; an analog-to-digital conversion circuit configured to perform digital sampling on the amplified signal to generate a plurality of analog-to-digital conversion signals; a feed forward equalization circuit comprising a plurality of feed forward equalizers, the plurality of feed forward equalizers being configured to perform feed forward equalization on the plurality of analog-to-digital conversion signals to generate a plurality of feed forward equalization signals; and a masking bit control circuit configured to generate a first masking bit control signal associated with the feed forward equalization, wherein the plurality of feed forward equalizers includes a first feed forward equalizer configured to generate a plurality of first tap output signals based on a plurality of first analog-to-digital conversion signals among the plurality of analog-to-digital conversion signals, adjust a digital value of each first tap output signal of the plurality of first tap output signals based on the first masking bit control signal to generate a plurality of first masking signals, and generate a first feed forward equalization signal of the plurality of feed forward equalization signals based on the plurality of first masking signals.
