What are the applications of photodiode?
The photodiode is widely use in day to day life means in consumer electronics and in industry. Application of photodiodes. The photodiode is used in an optical communication system. The…
Can an LED be used as a photodiode?
In most circuits, you can replace a standard silicon photodiode with an LED. Pay attention to the polarity. Also keep in mind that the LED is not as sensitive as…
What is IR photodiode?
An IR sensor is basically a device consisting of a pair of an IR LED and a photodiode, collectively referred to as photocouplers or optocouplers. The IR LED emits IR…
How does photodiode detect light?
LEDs can also be used as photodiodes because they can emit and sense light from their junction. All PN junctions are photosensitive and can be used in a photoconductive, undistorted…
How is photodiode used to detect optical signals?
A photodiode may be used to detect optical signals as we observe the change in current with change in light intensity when a reverse bias voltage is applied. Under a reverse…
What is the difference between Photodiode and phototransistor?
One of the major differences between the photodiode and the phototransistor is that the photodiode uses a PN junction diode that converts the light energy into electrical current while the…
What is meant by avalanche photodiode?
An avalanche photodiode (APD) is a highly sensitive electronic semiconductor device that utilizes the photoelectric effect to convert light into electricity. High sensitivity and low noise, Fast reaction and Low-light…
How does an AC motor work?
How does an AC motor work? There are two main aspects of an AC motor stator and a rotor, the supply is supplied (three-phase or single-phase) to the stator that…
What is an electric motor?
Any device using the interaction between an electrically generated magnetic field and another magnetic field generated electrically or naturally to function. According to this definition, for example, the electric solenoid…
How does a MOSFET have lesser conduction losses power consumption than a BJT in switching applications?
MOSFETs are unipolar devices, i. H. There is only one type of carrier in action, generally electrons. BJTs are bipolar devices, i.e. H. Both electrons and holes conduct electricity within…
What makes sensors work?
Most sensors use radiation such as light or laser, infrared waves or other waves such as ultrasonic waves to detect objects and changes in their surroundings. They can do this…
Is MOSFET a bidirectional device or unidirectional device What is a clear explanation about this?
The MOSFET is a symmetrical device in which the source and drain can be interchanged (if the body is not short-circuited to the drain or source). The MOSFET transistor is…
Why do we need of biasing?
Bias: is a term from no less than 400 years, which means “oblique or diagonal line”. It is not an error of assessment, it is a preference. If you research…
