Receiver and associated control method

摘要

A receiver is provided. The receiver includes a CTLE receiving a received signal, and generating a first equalized signal by processing the received signal according to a pole and a boost level; a slicing circuit coupled to the CTLE, generating a data signal according to the first equalized signal and a feedback equalization signal; a DFE coupled to the slicing circuit, generating the feedback equalization signal by processing the data signal according to a DFE coefficient set. Furthermore, the boost level is adjusted according to a first DFE coefficient of the DFE coefficient set, while the pole is adjusted according to the second and third DFE coefficients.
