Signal receiving device

A signal receiving device, comprising:

• an analog front end circuit, processing an input signal to generate a plurality of first signal pairs;
• a plurality of adders, respectively receiving the first signal pairs, each of the adders adding each of the first signal pairs with a plurality of first parameters to generate each of a plurality of second signal pairs;
• a plurality of first splitter sets, respectively corresponding to the adders and sampling the second signal pairs to respectively generate a plurality of sampled data according to a reference data pair based on a second parameter;
• a plurality of second splitter sets, respectively corresponding to the adders, a plurality of selected splitter sets among the second splitter sets sampling the corresponding second signal pairs to respectively generate a plurality of first error information according to a reference voltage pair based on a correction parameter, and at least one unselected splitter set among the second splitter sets sampling each of the corresponding second signal pairs to respectively generate second error information according to the reference voltage pair based on the second parameter;
• and
• a clock recovery circuit and a decision feedback equalizer, respectively generating a plurality of received data corresponding to the input signal according to the first error information and the second error information.
