An amplifier amplifies the small input signal to a high signal without changing its freqency.
An amplifier with tuned filters on both input and output.
Without an amplifier.
an amplifier, where the resistor and capacitor get coupled to provide high oscillations hence by which amplifications increases at high degrees
The internal gain of an amplifier is the gain or the amplification factor of the transistor used in it....................it is internal because it is fixed for transistors while manufacturing..................
A swamped amplifier has a resistance tied to the emitter of the NPN transistor. Swamping the amplifier reduces the voltage gain. When an amplifier is swamped the voltage gain to the output is less dependent on the load. This helps to balance the output and protect the circuit when different loads might be applied.
Darlington amplifier has more gain when compared to cascade amplifier .
1.differential amplifier 2.operational amplifier 3.instrumentation amplifier 4.chopper amplifier 5.isolation amplier
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
In audio look at an amplifier. It will be always a voltage amplifier.
