Abstract
The invention provides a method for automatically adjusting the gain of a multi-stage equalizer of a serial data receiver, the serial data receiver provides a gain circuit, the gain circuit comprises a multi-stage equalization circuit, and each stage of equalization circuit is arranged in series; the method comprises: Step S1, setting corresponding serial numbers for each stage of equalization circuit in sequence; Step S2, selecting an equalization circuit corresponding to the serial number from the gain circuit according to a preset rule; Step S3, sequentially adjusting the selected equalization circuits of each stage according to the sequence of the serial numbers to obtain corresponding standard adjustment values; and Step S4, adjusting the equalization circuit greater than or equal to the corresponding serial number according to the standard adjustment value. The method has the benefits that the optimal compensation for the signal is realized.
