Simple MOSFET Switching Circuit – How to turn on / turn off N-Channel and P-channel MOSFETs A MOSFET is a type of transistor that uses an electric field to control current flow, and is widely used in switching and amplification circuits. MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor, which has a gate. For simplicity, you can imagine this gate like a water tap. You rotate the tap counter-clockwise the water starts flowing out of the tap.… |

Understanding the Difference Between BJT and MOSFET and How to Select the Right One for Your Designs If you are exploring the world of electronics, and you want to know more about the Transistors and MOSFETs for your upcoming brilliant project, you are at the right place. In this article, we will discuss the basics of BJTs, Transistors, and MOSFETs. Before semiconductors (particularly transistors), the only devices available for signal amplification and switching were… |

Current Mirror Circuit: Wilson and Widlar Current Mirroring Techniques In the previous article, we discussed about Current Mirror Circuit and how it can be built using a Transistor and a MOSFET. Even though a basic current mirror circuit can be constructed using two simple active components, BJTs and MOSFETs or using an amplifier circuit, the output is not perfect, as well as it has certain limitations and dependencies on the external factors.… |

RC Phase Shift OscillatorWhat is Oscillator?
An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. We all have devices which need oscillators, traditional clock that we all have in our home as a wall clock or wristwatch, various type of metal detectors, computers where microcontroller and microprocessors are involved all… |

PNP Transistors The first bipolar junction transistor was invented in 1947 at Bell laboratories. “Two polarities”is abbreviated as bipolar, hence the name Bipolar junction transistor. BJT is a three terminal device with Collector (C), Base (B) and Emitter (E). Identifying the terminals of a transistor requires the pin diagram of a particular BJT part. It will be available in the datasheet.… |
