Here’s a simple FET circuit that lets you switch ... Speaking of the Pinecil, it uses an unorthodox driving circuit – it has an NPN transistor, but its base driven through a capacitor, so ...

[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 ...

In this lesson, students build two circuits and explore how transistors ... The diagram illustrates the basic design of an NPN junction transistor. Two slices of N-type semiconductor, the emitter ...

This transistor switching circuit uses an npn transistor, a voltage divider (consisting of a \(5 kΩ \) resistor and thermistor) and a \(5 V\) power supply. Use the information in the table to ...
