Patent ID: 11863356
Assignee: QUALCOMM INCORPORATED
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. An apparatus, comprising:
means for equalizing a signal received from a communication channel, including a first equalizer circuit that includes a first source degeneration circuit that has a first source degeneration resistor coupled in parallel with a first source degeneration capacitor; and
means for applying a gain to the signal received from the communication channel, including a first trans-impedance amplifier (TIA) in the first equalizer circuit, wherein the first TIA includes 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.
