Imagine for a moment a simple transistor circuit involving a single NPN transistor with its emitter grounded, its collector tied to the positive supply by a resistor, and a potentiometer between ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a ...

Circuit diagrams often show transistors in switching circuits. For an ideal NPN transistor, the switch-on voltage at the base is typically 0.6V (acceptable range is 0.6V to 0.8V). This means that ...

Linear Technology's recently introduced LTC4300 chip buffers I 2 C clock and data lines to and from a hot-swappable card. This task is difficult because the IC must work bidirectionally, meaning that ...

What is a Programmable Unijunction Transistor (PUT)? Simple – it is ... in this oscillator circuit is a good sawtooth (but do not load it much as it is at a high impedance). Also, the current out at ...

This simple device can be used to create complex electronic circuits, and although there ... Let’s take a closer look at how NPN and PNP transistors work. There are two main types of transistor ...
