Biasing That Transistor Part 4: Don’t Forget The FET
A FET is a voltage amplifier rather than a current amplifier, its input impedance is many orders higher than that of a bipolar transistor, and thus you will find FETs used in many applications ...

Lesson 4
The transistor acts like an insulator or a switch that is turned off. When a positive voltage is applied to the base, electrons are pulled out of the junctions and they no longer act as barriers.

Transistors explained – what they are and what they do
It carries the capability to manage or modify current or voltage flow, amplify and produce electrical signals, and act as a switch or gate. The impressive fact is that trillions of these transistors ...

FET: The Friendly Efficient Transistor
If you want to control it from a 3.3 V MCU that can’t handle the high-side voltage on its pins, you can add a NPN transistor section as shown – this inverts the logic, making it into a more ...
