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 ...

Abstract: An equivalent circuit model for large-area PIN photodiodes used in visible light communication (VLC) applications is described. The modelling aims to gain insight into the effect of the ...

Abstract: In this work we present a new physically based electrical equivalent circuit (EEC) of a photodiode. This EEC is capable to correctly predict the behaviour of the diode and can be used as a ...
