Classification: CPC H | IPC H

Claim 1:
2. The receiving circuit of claim 1, further comprising:
a second equalizer circuit coupled in series with the first equalizer circuit including:
a second source degeneration circuit that comprises a second source degeneration resistor coupled in parallel with a second source degeneration capacitor; and
a second TIA comprising 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,

wherein the third variable feedback resistor and the fourth variable feedback resistor are configured to control a second gain that is provided by the second equalizer circuit, and
wherein resistance values of the third variable feedback resistor and the fourth variable feedback resistor are controlled by a second control input received at the second equalizer circuit.
