Detailed Solution
Download Solution PDFAmong the following options, the photodiode has superior bandwidth and temperature stability.
1.) Photodiode
- A photodiode is a PN-junction diode that consumes light energy to produce an electric current.
- They are also called photo-detector, light detectors, and photo-sensor.
- Photodiodes are designed to work in reverse bias conditions.
2.) Light-emitting diode
- A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it.
- LEDs are designed to work in forward bias conditions.
3.) Zener diode
- The zener diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached.
- The main use of a zener diode is to act like a voltage regulator.
4.) PN diode
- PN diode is a two-terminal semiconductor device that is used for allowing electric current in one direction.
- PN diode conducts only when it is in forward-biased condition.
