A2. For amplification to take place, one needs three terminals; an input, an output, and a control signal.
This indicates the original " valve" naming; after a mechanical valve, where a small effort on a (hydraulic) valve may be used to control a larger effort of the controlled fluid.
A1. If u meant why diode can't be used as an amplifier diode is used as a rectifier..
it converts ac current to dc and there is an inbuilt voltage drop... so it can't be used as an amplifier
What else can I help you with?
Can a pn junction diode be used as an amplifier?
Never. It is impossible to use diodes for amplification.
How diode can be used as a thermometer?
yes it can. i cant believe you didn't know that.
How can you make a bypass diode?
the diode is forward bias ANSWER: A bypass diode is used to bypass circuitry as soon as the diode is forward bias by 0.6 volts The use it to bypass to prevent damage to the circuitry
What is the configuration of cascade amplifier?
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
What is a precision diode?
A precision diode is a diode with 0V (or near 0V) voltage drop when forward biased, unlike a normal diode which has a finite forward voltage drop of typically 0.2 to 0.8V depending on diode technology.It is typically implemented with an Operational Amplifier that has a normal diode somewhere in it's feedback path. The circuit utilizes the gain of the Op-Amp to compensate for the finite voltage drop of the diode. Several variations of the implementation exists.Some applications for precision diodes areRectification or detection of signals with low amplitudeVoltage gating (selection of the highest or lowest of several voltages)Voltage references (replacing Zener diodes)
How do you use a diode as temperature sensor?
The voltage across a Silicon Diode junction varies 0.00011 volts per degree Kelvin. Connect the diode to a high gain amplifier and the output of the amplifier to a DVM using an appopriate voltage scale.
What is the use of superdiode?
superdiode consist of diode and amplifier circuit.it is used for the rectification of small signals
Can a pn junction diode be used as an amplifier?
Never. It is impossible to use diodes for amplification.
When diode is used as an amplifier it is operated in what?
Diodes are not amplifiers.
Is zener diode a voltage amplifier or currentlimitig circuit or osilator circuit?
The zener diode is neither a voltage amplifier nor a current limiting device but can be used in oscillator circuits to supply a constant output voltage.
Can you use diode as trangister?
A: YES but not directly. for instance a discrete differential amplifier one side need to be a transistor to recover gain but the other transistor can be a diode since in real time that is the operative base to emitter current difference. .
What has the author Charles Thomas Key written?
Charles Thomas Key has written: 'IMPATT diode amplifier'
What is use of the diode?
The use of the pn diode is for rectification. It can also be used as a switch.
Can you use resistance in place of diode in clipping circuits?
no we not use resistance in place of diode.
How diode can be used as a thermometer?
yes it can. i cant believe you didn't know that.
Which diode does not use negative resistance in its operation?
Backward diode
Why mostly a transister is used as amplifier than diode?
A diode is not an amplifier. It is a rectifier with asymmetrical voltage breakdown voltages. Usually the forward voltage is around 0.6V to 0.7V (silicon), and the reverse voltage is smaller than breakdown voltage, which is much higher. A transistor can be used as an amplifier, by taking into account the fact that the voltage breakdown curves vary, usually collector-emitter, as a function of some other current, usually base-emitter, but this depends on the class of the amplifier and whether or not the transistor is driven into saturation.
