The transimpedance amplifier uses an op-amp and a feedback resistor to generate an output voltage that is proportional to an input current. The magnitude of the gain is equal to the feedback resistance, and since inversion occurs, the circuit''s transfer function is ( V_ {OUT} = - I_ {IN} times R_F ).
