Transimpedance Amplifier with Feedback Resistor vs Tee Network

Description

two current-to-voltage converters are implemented with different solutions: an operational amplifier OPA637 with feedback resistor and the same operational amplifier in a Tee network configuration. The first solution shows a lower noise, and therefore a higher signal-to-noise ratio, a lower DC offset and drift. These devices are used as high sensitivity transimpedance photodiode amplifiers, the current source represents the photodiode.
