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.
