Amplifier Distortion

A mplifier distortion occurs because the amplifier is not linear and a type of amplifier distortion called Amplitude Distortion will result. Careful choice of the transistor and biasing components...

Class C Amplifier

The Class C Amplifier design has the greatest efficiency but the poorest linearity of the classes of amplifiers mentioned here. The previous classes, A, B and AB are considered...

Class AB Amplifier

Class AB Amplifier As its name suggests, the Class AB Amplifier is a combination of the “Class A” and the “Class B” type amplifiers we have looked at above....

Class B Amplifier

Class B amplifiers were invented as a solution to the efficiency and heating problems associated with the previous class A amplifier. The basic class B amplifier uses two complimentary...

Class A Amplifier

Class A Amplifiers are the most common type of amplifier class due mainly to their simple design. Class A, literally means “the best class” of amplifier due mainly to...

Amplifier Classes

Generally, large signal or Power Amplifiers are used in the output stages of audio amplifier systems to drive a loudspeaker load. A typical loudspeaker has an impedance of between...

Bipolar Junction Transistor-BJT

he bipolar junction transistor, BJT, is the cornerstone of much of today’s semiconductor electronics industry. This form of transistor has been in existence for many years and is still...

MOSFET

The term MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor, and the name gives a clue to its construction. The devices had been known about for several years...

Transistor Darlington Pair

The Darlington Pair is a useful circuit configuration for many applications within electronic circuits. This circuit configuration provides a number of advantages that other forms of transistor circuit are...

HYBRID EQUIVALENT FOR CC TRANSISTOR

The figure shows the transistor connected in common emitter configuration and the figure also shows the hybrid equivalent circuit of such a transistor.  In common emitter transistor configuration, the...
