The aim of the project is to measure the distance between the photodiode (sensor) and the LED (input) using ARDUINO micro. Two states of the sensor were implemented: calibration and measurement states ...

In this paper, an improved single-photon avalanche photodiode (SPAD) equivalent circuit model is proposed. As a high-performance optoelectronic device, SPAD has ...

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 macro model ...
