Crossover Distortion in Amplifiers
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
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
For a signal amplifier to operate correctly without any distortion to the output signal, it requires some form of DC Bias on its Base or
Common Emitter (CE) amplifiers are designed to produce a large output voltage swing from a relatively small input signal voltage of only a few millivolt’s
To improve the full power efficiency of the previous Class A amplifier by reducing the wasted power in the form of heat, it is possible
Transistor amplifier circuits such as the common emitter amplifier are made using Bipolar Transistors, but small signal amplifiers can also be made using Field Effect
In the previous introduction to the amplifier tutorial, we saw that a family of curves known commonly as the Output Characteristic Curves, relate the transistors Collector

In an Alternating Current, known commonly as an “AC circuit”, impedance is the opposition to current flowing around the circuit. Impedance is a value given in Ohms that is
Power Factor Correction is a technique which uses capacitors to reduce the reactive power component of an AC circuit in order to improve its eficiency and
In a DC circuit, the power consumed is simply the product of the DC voltage times the DC current, given in watts. However, for AC
