Title:
DECISION FEEDBACK EQUALIZATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/121106
Kind Code:
A1
Abstract:
Disclosed is a decision feedback equalization circuit. The decision feedback equalization circuit comprises: a first adder circuit configured to add sampled data, first correction data, and target correction data; a first sampler configured to sample, by means of a first signal component in a first clock signal, data output by a first adder to obtain a first sampling result; a second adder circuit configured to add the sampled data, the first correction data, and the target correction data; a second sampler configured to sample, by means of a second signal component in the first clock signal, data output by a second adder to obtain a second sampling result; and a correction parameter processing unit configured to determine the target correction data by means of a second clock signal, the first sampling result, and the second sampling result.
