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 ...

Abstract: On-chip germanium-silicon (Ge-Si) photodiodes are critical elements to advancing the inclusion of silicon photonics in integrated circuit design. Understanding their radiation tolerance is ...

Your requirements are not going to be trivial--- A photodiode with 40 pF @ -10V will be difficult to deal with if you need much sensitivity from your fast photodetector circuit. A much smaller PIN ...

If I have 25 photodiode and one ADC,how to design transimpedance amp circuit ? I have cost issue,so I can not use 25 transimpedance amp circuit. Could I use analog switch to switch these 25 photodiode ...
