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: 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 ...
Abstract: In this paper, a novel equivalent circuit model for the frequency performance of separate absorption grading charge multiplication (SAGCM) avalanche photodiode (APD) is developed. This model ...
