In addition, there is a very wide range of integrated circuits ... source) the behavior of a BJT is vastly more linear than when used as a voltage amplifying stage, for which the input voltage/output ...

The conventional solutions employ concepts based on tone generation/reflection or current-source circuits ... shows a low-cost solution based on a transistor switch (Q1). The transistor is ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become ... build what they called "unitary circuits" and they also applied ...

laying a foundational framework that parallels the success of classical transistor models in electronics. By enabling clearer visualization, simulation, and design of quantum thermal circuits ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can ...
