If the base current varies, so does the output current, which is how a transistor functions as an amplifier. It’s similar to the way you control the flow of water with a faucet. With a small ...

Enter an old Radio Shack P-Box stereo amplifier kit ... The Radio Shack kit used germanium transistors, but with their high leakage current and low thermal conductivity, he decided to convert ...

(Image: Azal Alothmani, Lund University) When working as an amplifier, a transistor transforms a small input current into a bigger output current. As a switch, it can be in one of two distinct states ...

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 ...

Advances in materials and architecture could lead to silicon-free chip manufacturing thanks to a new type of transistor.

Researchers propose 3D semiconductor architectures using 2D semiconductor materials for better performance and scalability ...

The first transistor was about half an inch ... This contraption was the very first semiconductor amplifier, because when a bit of current came through one of the gold contacts, another even ...
