MOSFET: how does it work?

Pedro Ney Stroski / 17/02/2023

The MOSFET is another type of field effect transistor. Much more used than JFET and it’s the most important component for digital computers.

The junction field effect transistor (FET) is a component with many applications. In this post, are shown the structure and the operation.

The common base is little known configuration for amplifiers using BJT. This type is used in high frequencies.

This is a project of a vehicle with tracks controlled by a pair of RF modules and intergated circuits HT-12E (encoder) and HT-12D (decoder).
