Two-dimensional high-speed equalizer with programmable direct current (DC) and peaking gains

An equalizer comprising:

• a first signal path segment that comprises a first plurality of serially connected transistors and current sources;
• a second signal path segment that comprises a second plurality of serially connected transistors and current sources;
• and
• a plurality of termination resistors connected to the first and second signal path segments and connectable to a supply voltage,
• wherein the first signal path segment has a first transfer function, wherein the second signal path segment has a second transfer function that is different from the first transfer function, wherein the first signal path segment has a first peaking gain, and wherein the second signal path segment has a second peaking gain that is higher than the first peaking gain.
