Abstract: A signal conditioner that includes a transition-detection module and a current-injection module. The transition-detection module is configured to receive a pair of differential signals from a data line and generate one or more comparator output signals and a transition-indication signal to indicate whether a transition has been detected on the differential signals. The current-injection module is configured to receive the comparator output signals and transition-indication signal from the transition-detection module, and generate appropriate currents for injection into the data line to boost edge rates of the differential signals when the transition-detection module detects a transition of the differential signals or remain high impedance when no transition occurs on the differential signals.
