The Common Collector Amplifier is another type of bipolar junction transistor, (BJT) configuration where the input signal is applied to the base terminal and the output signal

The Common Base Amplifier is another type of bipolar junction transistor, (BJT) configuration where the base terminal of the transistor is a common terminal to both the

The purpose of any amplifier is to produce an output which follows the characteristics of the input signal but is sufficiently large enough to supply

In our previous tutorial about FET amplifiers, we saw that simple single stage amplifiers can be made using junction field effect transistors, or JFET’s. But

Amplifiers and filters are widely used electronic circuits that have the properties of amplification and filtration, hence their names. Amplifiers produce gain while filters alter

The steady state operation of a transistor depends a great deal on its base current, collector voltage, and collector current values and therefore, if the

Input Impedance, ZIN or Input Resistance as it is often called, is an important parameter in the design of a transistor amplifier and as such allows amplifiers to be

Not all amplifiers are the same and there is a clear distinction made between the way their output stages are configured and operate. The main

We have seen that one of the main disadvantages of the Class-A Amplifier configuration is its low full power efficiency rating due to being biased around its

Generally we think of Amplifiers as audio amplifiers in the radios, CD players and stereo’s we use around the home. In this amplifier tutorial section we looked

The aim of an AC signal amplifier circuit is to stabilise the DC biased input voltage to the amplifier and thus only amplify the required
