How do you bias photodiode?

As the applied reverse bias increases, the photodiode current increases sharply. The blocking voltage applied at this point is called the breakdown voltage. This is the maximum applied reverse voltage…

Why photodiode is heavily doped?

Light enters the photodiode region which is not folded and causes the formation of electron-hole pairs. Under the action of the electric field, electrons migrate to the avalanche region.

What is photodiode responsivity?

The responsivity of a photodiode can be defined as the ratio of the photocopic current produced to the power of light that occurs at a certain wavelength. Responsivity (or radiation…

What is a light dependent resistor

What is a light dependent resistor? a ldr is a photo-conductive material. when the light is exposed to ldr, the electromagnetic radiation is sufficient to excite the electrons towards the…
