A class D amplifier is basically a category of amplifier in which the power devices (mosfets and BJTs) are operated like switches. The associated output devices in such amplifier circuits either turn fully ON or fully OFF, but never switch between other undefined levels ensuring minimal heat dissipation and maximum efficiency from the devices.

2 watt Amplifier Circuit
A very simple 2 watt audio amplifier circuit has been presented here which can be constructed by all new electronic hobbyists for amplifying small signal frequencies and for other similar experiments. Circuit Operation
Amplifier Short/Overload Protection Circuit – 2 Ideas Discussed
Due to some reason if the loudspeaker of a power amplifier gets shorted, that may lead to a fatal damage to the amplifier component. To prevent this an amplifier short circuit protector circuit can be very useful. In the following post I have explained 2 simple amplifier short circuit or overload protection circuits for safeguarding […]
DIY 100 Watt MOSFET Amplifier Circuit with PCB
MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easily beat the performance of other counterparts based on power transistors or linear ICs. Why use MOSFETs in Amplifiers Amplifiers based on mosfets are not always easy to design or make. Moreover after assembling a prototype, testing to perfection […]
How to Make a Telephone Amplifier Circuit
The simple telephone ring tone amplifier circuit I have explained in this article saves the inconvenience of picking the telephone handset while speaking over a call. This circuit also particularly becomes useful when there’s a need of the conversation to become audible to a number of people or a group of people. Introduction When the […]
How to Make Active Loudspeaker Circuit
In this post I have explained to make an active loudspeaker system circuit for enabling self sustained amplification of any music source that may be directly plugged in to the active speaker box. Introduction With the advent of ultra modern cell phones, now it has become possible to store huge music data and listen to […]
