The output current of a PIN diode is proportional to the light incident . Whereas in APD due to internal multiplication (Avalanche multiplication) of primary photocurrent, higher gains are possible.
A small signal current output from the pin diode are to be amplified before applying to next associated receiver circuit. This includes thermal noise in the main signal, giving lower, receiver sensitivity. In case of APD, photocurrent is multiplied before encountering the thermal noise amplifier, giving increased receiver sensitivity.

What is diode clamping?
There are a couple types of diode clamping-- A P-N diode was often used for clamping coils of relays that produce high voltages when the relays is de-energized. Bidirectional zeners are now the best solution. Diode clamping is also a term used to limit voltage excursions generally. Zener diodes are generally used for this purpose.
The most common device used for detection in radio receivers is?
DIODE
Application of PN junction diode?
Application of Pn junction diode is a very vast topic itself. It is used in almost every electronic circuits.diodes are used to build half wave and full wave rectifiers.they are used to convet AC to DC.
What was the photo eminem picked up in the house in 8 mile movie?
If u mean the one they burn its A picture of the family who used to live there
What does the LED do in the curcuit?
The main function of an LED (Light Emitting Diode) is simply to show a "light." LEDs can be used singularly, as in a hand torch, or in groups, as in the lights used on vehicles, and illuminated signboards, etc. The advantage of LEDs over conventional filament bulbs is low power requirements, long life and robustness.
What is the different between photo-diode and LED?
A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.
Which type of diode used in bridge rectifier?
You can use most diodes for that purpose, and particularly silicon diodes. However, you should not use zener diodes and similar for rectification purposes. Otherwise, you will likely not get the intended result. If the voltage exceeds the avalanche voltage, then the zener diode will no longer rectify, but conduct the other way as well.
What is blocking diode?
any diode if connected to where the anode is tie to a negative potential will block that voltage. Up to the limit of the breakdown potential of the diode whereby avalanche current will destroy the diode unless current limited
What is avalanche voltage?
Avalanche voltage is the voltage value that causes a reverse-biased semiconductor junction to break down and conduct. Sometimes this is undesirable. A rectifier diode in a power supply that avalanches has failed. It can also be desirable. A Zener diode used as a regulator works by avalaching at a specific voltage, thus limiting the circuit voltage at that level.
What is diote?
A diode is semiconductor device which is used in a lot of application in electronics equipment.it is negative temp. coefficient device i.e. at lower temp. it is behave like a insulator and high temp. it is work like a good conductor. Basically a diode is used to convert an alternating current into direct current in form of a rectifier. There are many types of diode used in today day to day life depends upon their application. 1 crystal diode 2 photo diode 3zener diode are some of the most useful diode.

Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is photo sensitive diode and how it works?
A diode that is sensitive to light. As light increases, the diode resistance drops. This can be used as a sensor in control circuitry that directs solar panels so they are always facing the sun. They also can be used to automatically turn on street lights, garden lights, among many other applications.
What is the function of diode what is the function of diode?
A diode is used primarily as a Rectifier
Can a zener diode act as a surge protector?
Yes, and it's quite common to see one used as such. Whenever the voltage exceeds the rating of the diode, the diode will conduct and usually short circuit the excess voltage to ground. It's been commonly called a `crowbar circuit' and using the diode, it can be configured in several different configurations, depending on your application. A zener designed for such applications is often called a TVSS or avalanche diode. These feature lower incremental resistance, faster response times, lower leakage currents, and smaller capacitance as compared to conventional zener diodes. Downside of a zener diode is its tiny power handling abilities. Similar function is also performed using a Silicon Controlled Rectifier (SCR) for DC or a thyristor (triac) for AC.
Can you produce electricity even without magnetism?
yes we can produce electricity without magnetism by using semiconductor for example photo diode is used in solar cells.
Can diode be used as rectifier?
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
