Combination scheme for baseline wander, direct current level shifting, and receiver linear equalization for high speed links

A method comprising:

• receiving, by a first circuit, a differential input signal on first and second signal paths;
• providing, by one or more first current sources, current to or sinking current from the first signal path;
• providing, by one or more second current sources, current to or sinking current from the second signal path;
• passing one side of the differential input signal through a first receiver-capacitor parallel arrangement to a third signal path;
• providing, by one or more third current sources, current to or sinking current from the third signal path;
• passing one side of the differential input signal through a second receiver-capacitor parallel arrangement to a fourth signal path;
• providing, by one or more fourth current sources, current to or sinking current from the fourth signal path;
• and
• providing, on the third and fourth signal paths, an output version of the differential signal to a second circuit.

A system comprising:

• a first resistor comprising:
• a first leg connected to a first line of a first interface;
• and
• a second leg connected to a first line of a second interface;
• a first current sink connected to the first line of the first interface;
• a first current source connected to the first line of the first interface;
• a second current sink connected to the first line of the second interface;
• and
• a second current source connected to the first line of the second interface.
