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 ...

Abstract: Transistor biasing for RF-amplifiers typically is based on achieving the highest transistor speed given by the maximum oscillation frequency. However in low-power applications such as active ...

Why it matters: Silicon transistors are great, but just like any other object in the physical world, they are held back by a few limitations. The laws of physics put a bottleneck on performance 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 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 ...

Bias control of PAs is crucial to ensure optimum radio performance under all conditions. Current sensing and temperature sensing provides the feedback needed to control the PA bias. The choice of ...
