Simple Curve Tracer Circuit: Tracing the Curve for Resistor, Diode and Transistor Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor’s straight VI line or a transistor’s collector voltage versus current curve. These curves give us an intuitive understanding of how a device behaves in a circuit. An analytical approach might involve plugging in discrete… |

Bootstrap Amplifier Circuit using Transistors Amplifiers are integral part of Electronics which are used to amplify low amplitude signals. Amplifier plays a very important role to boost the signal, specially in Audio and power electronics. We previously built many types of amplifiers including audio amplifiers, power amplifiers, operational amplifiers etc. Apart from them you can learn many other commonly used… |

Simple H-Bridge Motor Driver Circuit using MOSFET At the outset, driving a motor might seem like an easy task – just hook the motor up to the appropriate voltage rail and it will start rotating. But this is not the perfect way to drive a motor, especially when there are other components involved in the circuit. Here, we will discuss one of the most commonly used and efficient ways to drive DC motors, the H-Bridge circuit.… |

Hartley Oscillator In simple terms, the oscillator is a circuit which converts DC power from the supply source to the AC power to the Load. Oscillator system is built using both active and passive components and it is used for the production of sinusoidal or any other repetitive waveforms at the output without any application of an external input signal. We discussed few oscillators in our… |

What is JFET: Its Construction, Working and Biasing Techniques JFET is a Junction gate field-effect transistor. A normal transistor is a current-controlled device which needs current for biasing, whereas a JFET is a voltage-controlled device. Similar to MOSFETs, as we have seen in our previous tutorial, JFET has three terminals: Gate, Drain, and Source. JFET is an essential component for precision-level voltage… |

Single Transistor Audio Mixer Circuit Audio Mixer is an essential device in Audio Electronics. The mixer mixes two or more audio signals into a one (Mono) or two output (Stereo). The audio mixer uses audio mixing process where multiple sounds are combined to form a single or multi-sound. It is a widely used process in Live concerts, televisions, films, music industries etc. In this… |

Simple White Noise Generator Circuit Every single circuit designer uses different techniques to remove noises from their circuit design. Noise is one of the main issues while building any circuit specially related to Audio or Power Electronics, but today, we will make a circuit which will produce noises. A special type of noise denoted as White noise. What is white noise?… |

100 Watt Power Amplifier Circuit using MOSFET Power amplifier is the part of audio electronics. It is designed to maximize the magnitude of the power f given input signal. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load. In this tutorial, we will build a 100W RMS output power amplifier circuit using … |

How to Build FM Transmitter Circuit One of the cool projects I always wanted to build is an FM transmitter with a good range. I have always been fascinated by some of the applications of the transmitter, especially when I was younger and, like everyone else, spent most of my time imagining how cool it would be to have some of the equipment and devices used in spy movies. So recently, while going over one of my… |

How to make Solar Inverter Circuit We have limited natural resources and that too we are using in generating Electricity. That’s why there is lot of emphasis is given on generating and using clean energy. Today in this project, we will see how electricity can be generated from the sunlight, how it can be stored in the form of DC, and then how it is converted into AC to drive home appliances. … |
