The electronic goods of the dynamic world need different varieties of amplification based on type of application or usages. Hence amps become the mandatory component of each electronic items utilized by the people.
The power amplification equipment raise the strength or energy of the resultant signal and modify the signal into more powerful than the inward signal. There are many different types of amplifiers available in the electrical and electronics markets.
The standard of an amp determined using parameters like bandwidth, noise, skew rate, gain, stability, linearity, efficiency, and outward dynamic range. The best amplifying device is the one which has low noise, high stability and faster bandwidth rate.
Categories of Amps
The study of the classification of amplifiers enables people to have profound knowledge in applications, functionalities and properties of the devices.
The amp devices divided into four main types depending on the inward and outward behaviors of the amps.
Volt based amp
The functionality of the tool determined using the name of the amplifying device that increases the inward voltage for a given higher or larger outward voltage. The characteristic of this amp device is a high inward impedance and low outward impedance. The applications of these voltage amps are small and large electronic devices.
Ampere based amp
The name itself indicates the functionality of the electronic amp that amplifies the inward current. The characteristic of this amp is reverse of the voltage amp where the inward impedance is low while outward impedance is high.
The amp changes or modifies the outward current according to the changing inward voltages.
The amp is one main types of amplifying devices that modify or change the outward voltage according to the changing current called as the current to voltage transformer or converter.
There are some other types of amplifiers classes based on the characteristics or operations or applications of the amps.
Electric Power amps
The aim or functionality of the power amp is to increase or maximize the power, which the product of the outward voltage and the outward current and it must be less than the inward current and voltage.
The current or voltage at the outward or resultant end is less whiles the net voltage value or current product is maximum or higher. The inward to this type of amps is the alternating current signal whose part is amplified and not the entire waveform gets changed. The experts classify the waveform based on the portion or area that is modified into four main type’s class A, class B, class AB and class C.
