Claim 19:
20. The method of claim 19, further comprising:
coupling the output of the first equalizer circuit to a first stage of a second equalizer circuit, the first stage of the second equalizer circuit including a second source degeneration circuit that has a second source degeneration resistor coupled in parallel with a second source degeneration capacitor;
coupling an output of the first stage of the second equalizer circuit to a second TIA that is provided in the second equalizer circuit, wherein the second TIA includes a third variable feedback resistor that is coupled between a first input of the second TIA and a first output of the second TIA and a fourth variable feedback resistor that is coupled between a second input of the second TIA and a second output of the second TIA; and
configuring resistance values of the third variable feedback resistor and the fourth variable feedback resistor to select a gain to be applied to the output of the first stage of the second equalizer circuit.
