| 摘要 |
A differential transimpedance amplifier circuit comprises a first operational amplifier having a first inverting input, a first non-inverting input, a first inverting output and a first non-inverting output. A second operational amplifier has a second inverting input, a second non-inverting input, a second inverting output and a second non-inverting output. The second inverting output communicates with the first non-inverting input and the second non-inverting output communicates with the first inverting input. A first feedback element communicates with the first non-inverting input and the first inverting output. A second feedback element communicates with the first inverting input and the first non-inverting output. A third feedback element communicates with the second inverting input and the first inverting output. A fourth feedback element communicates with the first non-inverting input and the first non-inverting output.
