I presented in a previous tutorial how to reconstruct a complex field using a camera and a plane wave reference tilted with respect to the optical axis, known as off-axis holography. This works ...

Educational tool for finding Q operating points of FET transistors (JFET and MOSFET) with different biasing configurations. Includes iterative, analytical, and graphical methods implemented in Python ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...

Ever since the development of the first working transistors in 1947, the electronics industry has experienced tremendous growth in numerous ways. For instance, transistors allowed for the ...

In a nutshell: Back in 2021, a team from the Massachusetts Institute of Technology made waves by creating an entirely new type of ferroelectric material. Now, those same researchers have one-upped ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

All thermal anemometers work by inferring air speed from measurements of thermal impedance (Z) between a heated sensor and the surrounding air: An example of the ...

A bipolar junction transistor (BJT) is a device that can amplify signals thanks to its two p-n junctions and three terminals: base, collector and emitter. This device is operated by current. At the ...
