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 ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Linear Technology’s Glen Brisebois, winner of an EDN Innovation award for best contributed article, noticed my JFET blog post and was nice enough to send along a note and some circuits he likes for ...

The new McPherson 671MX amplifier is a high vacuum compatible, current-to-voltage converting amplifier developed specifically for use with vacuum ultraviolet Silicon photodiodes. With integral ...

For photodiode-based designs requiring high-speed operation, the OPA380 transimpedance amplifier provides a gain bandwidth of 90 MHz with an offset of less than 25 µV and an offset drift of 0.1 µV/°C.

Analysis using spreadsheets can sometimes fill a gap in circuit simulation programs by providing a quick and reliable way to determine circuit performance along with the flexibility to display results ...

FEMTO Messtechnik GmbH supplies the variable gain transimpedance amplifier DHPCA-100 for amplifying photo currents of fast photodiodes, with a maximum bandwidth of 200MHz equivalent to a signal rise ...
