Push-Pull Amplifier Circuit Circuit schematics are crucial for electronics engineers to understand. For the majority of real-world applications, Class A amplifiers offer the lowest distortion, Class B amplifiers the most efficiency, and Class AB amplifiers the best resolution. The particular needs for power, distortion, and efficiency will determine the choice. A push-pull… |

Switching Buck Regulator: Design Basics and Efficiency In electronics, a regulator is a device or mechanism which can regulate power output constantly. There are different kinds of regulators available in the power supply domain. But mainly, in the case of DC to DC conversion, there are two types of regulators available: Linear or Switching. A linear regulator regulates the output using a resistive… |

Voltage Regulator Circuits Voltage Regulator, as the name suggests, is a circuit that is used to regulate the voltage. Regulated voltage is a smooth supply of voltage, free from any noise or disturbance. The output from the voltage regulator is independent of load current, temperature, and AC line variation. Engineers can create reliable power supply systems with the aid of these voltage… |

Voltage Follower using Opamp Voltage Follower is simply a circuit in which output follows the input, means output voltage remains same as input voltage. It is also commonly known as Unity gain Opamp Amplifier or Opamp Buffer. Here we construct a voltage follower using Opamp LM741 and see how its output follows the input. We already discussed about it in our Non-inverting Operational Amplifier tutorial,… |

Crowbar Circuit The reliability of any electronic device depends on how well the hardware protection circuits have been designed. The end user (consumer) is prone to make mistakes and it is the responsibility of a good hardware designer to protect his hardware from any mishappening. There are ample types of protection circuits each with its own specific applications. The most common type of… |

Voltage Controlled Oscillator (VCO) Most of the consumer electronic devices around us, such as mobile phones, TVs, Radios, and MP3 players, are a combination of Digital and Analogue electronics. Wherever wireless transmission/reception, or audio signals are involved in an electronic design, we will need periodic oscillating electronic signals. These signals are called Oscillating signals and are very useful in… |

RC, RL and RLC Circuits The entire range of electronic components can be divided into two broad categories: active components and passive components. The Passive components include the Resistor (R), the Capacitor (C) and the Inductor (L). These are the three most used components in electronics circuits, and you will find them in almost every application circuit. These three components together in… |

Cycloconverters – Types, Working and Applications Power supplies can be classified into two broad categories: AC power supply and DC power supply. Since only AC power can be generated economically, most electrical machines run on AC power. However, the standard voltage and frequency from generating stations may not suit certain industrial machines. This is where power electronic converters like inverters and cycloconverters… |
