What Is A Semiconductor Gate? The gate electrode is a thin film of a conductive material deposited on top of an insulator layer in a transistor. The gate sits above a channel formed in the main body ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

The new transistors (above) have vertical current-carrying channels. In older designs (inset), the channels lie flat under the gates. In an effort to keep squeezing more components onto silicon chips, ...
