Characteristics of Photo diode
There are two important characteristics of photo- diode. (i) Reverse current-Illumination curve. The below Fig shows the graph between reverse
Photodiode Working
Photodiode Working Principle
A photodiode is a semiconductor device that converts light into current. The current is generated when photons are absorbed in
Photodiode as Variable Resistance Device
The photodiode is a device that operates in reverse bias, as shown in Figure. where Ia is the reverse light
