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.
Can a schottky diode used as a current amplifier?
A Schottky diode is not typically used as a current amplifier; it is primarily designed for fast switching and low forward voltage drop applications. While it can conduct current efficiently, its function is to rectify or clamp signals rather than amplify current. Current amplification is generally achieved using transistors or operational amplifiers, which are specifically designed for that purpose. Therefore, while a Schottky diode can handle current, it does not provide current amplification.
Why is the rectifier diode never operated in the breakdown region?

What are two conditions under which diode is operated?
A diode is primarily operated in two conditions: forward bias and reverse bias. In forward bias, the positive terminal of the voltage source is connected to the anode and the negative terminal to the cathode, allowing current to flow through the diode. In reverse bias, the connections are reversed, preventing current flow and allowing the diode to block current, except for a small leakage current. These operating conditions are fundamental to the diode's function in circuits.
What is the use of finding the bandwidth of an amplifier?
A: Any amplifier will have greater band with if operated open loop. It will also be very unstable so negative feedback is implemented for that reason. There is some drawback when feedback the band width of the amplifier decreases, So is important to find out if the amplifier when stable will it have the band width required
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
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.
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.
Why diode can't use as amplifier?
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
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 are the system applications of a class B amplifier?
Class B operated amplifier is used extensively for audio amplifiers that require high power outputs. Its also used as the driver and power amplifier stages of transmitters.

Zener diode operates In an extremely high forward bias?
False, a zener diode is normally operated reverse biased in breakdown.
