1. A receiving circuit, comprising:
a first equalizer circuit including:
a first source degeneration circuit that comprises a first source degeneration resistor coupled in parallel with a first source degeneration capacitor; and
a first trans-impedance amplifier (TIA) comprising a first variable feedback resistor that is coupled between a first input of the first TIA and a first output of the first TIA and a second variable feedback resistor that is coupled between a second input of the first TIA and a second output of the first TIA,
wherein the first variable feedback resistor and the second variable feedback resistor are configured to control a first gain that is provided by the first equalizer circuit, and
wherein resistance values of the first variable feedback resistor and the second variable feedback resistor are controlled by a first control input received at the first equalizer circuit.
