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 12):
The chip according to  claim 8 , wherein the first circuit comprises a first capacitor, a first resistor and a second resistor, wherein the first resistor and the second resistor are coupled in series and coupled to the first capacitor in parallel, wherein one end of the parallel coupling is coupled to the current source and a negative input of the operational amplifier, wherein the other end of the parallel coupling is coupled to a first output of the operational amplifier, and wherein a coupling point of the series coupling between the first resistor and the second resistor is coupled to the third circuit.
