Abstract:
A trans-impedance amplifier (TIA) includes a first circuit, a second circuit, and a third circuit. Both the first circuit and the second circuit are coupled to a current source, an operational amplifier, and the third circuit. The first circuit is configured to receive a first current, provide a third voltage to the third circuit, perform shape filtering on the first current, and convert the shape filtered first current to a first voltage for output. The second circuit is configured to receive a second current, provide a fourth voltage to the third circuit, perform shape filtering on the second current, and convert the shape filtered second current to a second voltage for output. The third circuit is configured to cooperate with the first circuit and the second circuit in performing shape filtering. The operational amplifier is configured to provide a small-signal virtual ground point to the first circuit.

Claim (Index 20):
The communications device according to  claim 19 , wherein the second circuit comprises a second capacitor, a third resistor and a fourth resistor, wherein the third resistor and the fourth resistor are coupled in series and coupled to the second capacitor in parallel, wherein one end of the parallel coupling is coupled to the current source and a positive input of the operational amplifier, wherein the other end of the parallel coupling is coupled to a second output of the operational amplifier, wherein a coupling point of the series coupling between the third resistor and the fourth resistor is coupled to the third circuit, wherein the first capacitor and the second capacitor have a same capacitance, and wherein resistances of the first resistor, the second resistor, the third resistor, and the fourth resistor are the same.
