AN-1803 Design Considerations for a Transimpedance Amplifier (Rev. A)
Texas InstrumentsIt is challenging to design a good current-to-voltage (transimpedance) converter using a voltage-feedbackamplifier (VFA). By definition a photodiode produces either a current or voltage output from exposure tolight. The transimpedance amplifier (TIA) is utilized to convert this low-level current to a usable voltagesignal and the TIA often needs to be compensated for proper operation. This a
