Keywords:Photodiodes  transimpedance amplifier  photovoltaic  FET  op amp 

[Summary of tips] The current generated by photodiodes is proportional to the light that strikes their active area. Most measurement applications involve using a transimpedance amplifier to convert the photodiode current into an output voltage. Figure 1 shows a simplified schematic of what the circuit could look like.This circuit operates the ph......
