depends on the circuit it is used in:CE/CS is inverting voltage amplifierCC/CD is noninverting current amplifierCB/CG is noninverting voltage amplifier
It can be but it might not be, it depends on circuit design.
It is an amplifier that has no gain or a gain of one mainly used for isolation .
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain
Its purpose is to provide approximately the same voltage to a load as what is input to the amplifier, but at a much greater current. In other words, it has no voltage gain, but it does have current gain.
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
It's a buffer circuit - it provides a high impedance input, and low impedance output with ~ unity gain. If you have a circuit that cannot drive much power, you can use a voltage follower to help. Also, if the input or output of a circuit needs to stay a specific value, such as with filters, you can easily control this due to the isolation the voltage follower provides.
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.
It essentially boosts the voltage across the amplifier, and through the circuit.
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
