Abstract: Methods and systems are provided for processing a signal over a serial link. The methods and systems receive, by an adjustable filter, a serial input signal, the adjustable filter configured to set a corner frequency of a channel response and a gain of the channel response, the adjustable filter adding a zero to the channel response before to a pole of the serial input signal. The methods and systems selectively apply, by a bandwidth booster component, compensation to signal attenuation of the serial input signal in a first mode of operation and of one or more test signals in a second mode of operation of a serial link receiver. The methods and systems generate, by one or more continuous time linear equalizers configured to receive on an output of the bandwidth booster, one or more output signals of the receiver based on an output signal from the bandwidth booster component.
