Abstract:
1. Equalization circuitry comprising: a first resistor, a first transistor, and a first current source connected in series; an input node connected to a gate of the first transistor; an output node connected between the first resistor and the first transistor; a first coupling capacitor connected between the input node and a bias node of the first current source, the coupling capacitor creating a change in current through the transistor in response to a change in voltage at the input node; a second transistor, complementary to the first transistor, wherein the second transistor is coupled to a node between the first transistor and the first current source; a second current source connected in series to the second transistor; and a second coupling capacitor connected between a gate of the second transistor and a bias node of the second current source.
