Direct coupling is advantageous in many photodetector applications, such as viewing laser thresholds and modulation depth. I patented a very fast photodetector mount 1,2 in the early 1970s using these ...

Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltage signals, since many circuits and instruments can only accept voltage ...

In researching my latest article I ran across this paper about a “robust” photodiode amplifier (pdf). I use the scare quotes on purpose, since the whole article seemed a little fishy to me. The author ...
