Both the majority of class B or AB power amplifiers currently encountered in HI-Fi amplifiers are presented in the form of integrated circuits specifically designed for this purpose. It is interesting for technicians to know how this type of amplifier works, if only out of intellectual curiosity. The provided model allows the study of several […]
Newly Updated Circuit Projects:
Train Sound Simulator Circuit
The train sound simulator circuit is an electronic circuit that generates a realistic sound that mimics the sound of a train moving on tracks. The circuit is designed to be integrated into a model train set or layout to add to the overall realism of the scene. The sound is produced using a combination of […]
The Perfect FM Radio Circuit using TDA7000 IC
Here we are going to see how we can build a very simple, yet perfect FM radio circuit using one single IC called TDA7000. This IC already has everything inside it, so we do not need to do too much headache wiring around it. First of all, before we build, we must understand what each […]
Piano, Guitar Sound Effect Generator Circuit
Music is a part of our lives, accompanying and enhancing our everyday experiences. While it is easy in electronics to generate a single note, for example, using a simple astable oscillator, one can only dream of the myriad of sounds available on even the most ordinary synthesizers, versatile and almost indispensable instruments today. A musical […]
3.7 V Class D Speaker Amplifier Circuit for Differential Analog Input
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. […]
High Power 250 Watt MOSFET DJ Amplifier Circuit
The powerful DJ MOSFET amplifier circuit design provided in this article is reasonably easy to build and will produce a thumping 250 watts of music into a 4 ohm loudspeaker. Use of HEXFETs at the output ensures monstrous current and voltage amplification. The involvement of MOSFETs or rather HEXFETs at the output stage of this […]
