We have already discussed, theclasses and classifications of power amplifiersin our earlier articles. The power amplifier circuits are used to deliver high power to drive the loads likes loudspeakers. The power amplifiers are classified based on their mode of operation that is the portion of the i...

A method and circuits are disclosed for an operational amplifier operating from a single cell 1.5 Volt supply which consumes very little power, and which can handle rail-to-rail input common mode and output signal swings. Low voltage and low power operation are made possible by biasing the ...
A class C amplifier is biased so that it conducts for less than 180° of the input. It will typically have a conduction angle of 90° to 150°. This means that current flows through it in short pulses. The question is "How is a complete signal amplified?" As you will see, a resona...

the class of operation or mode of operation called amplifier classes. There are fourtypes of amplifier classes, they are Class A, Class B, Class AB, and Class C. This article gives a brief description of theclass AB amplifier, circuit diagram, working, applications, advantages, and ...
For amplification of the complete cycle it is necessary to use 2nd class B amplifier which functions for the negative half of the signal. The combine operation of 2 class B amplifier is known as the push-pull amplifier. There are 2 main techniques for a push-pull amplifier to generate a ...
