Classification: CPC H | IPC H

Claim 12:
13. The apparatus of claim 12, wherein the means for equalizing the signal received from the communication channel further includes a second equalizer circuit having a second source degeneration circuit that comprises a second source degeneration resistor coupled in parallel with a second source degeneration capacitor,
wherein the means for applying the gain to the signal received from the communication channel comprises a second TIA 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,
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 first second equalizer circuit.
