What makes it rather special is that it relies on only one type of device, every one of its transistors is a BC547. In design terms, it follows the lead set by other simple amateur transmitters ...

The circuit is a simple one, and a classic. The spring from a ballpoint pen is soldered to the base of a BC547 transistor, and when held close enough to a conductor carrying AC power, a current is ...

MIT researchers have developed a new type of 3D transistor that could be more energy-efficient and powerful than current ...

Edge computing devices, devices located in proximity to the source of data instead of in large data centers, could perform ...

and Field Effect Transistors (FETs). BJTs are controlled by current, while FETs are controlled by voltage. Within these categories, there are further subdivisions such as NPN and PNP BJTs and ...

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...

The transistor is considered to be one of the most important inventions of the 20 th century because of its abundant use in most modern circuits and electronic systems. NPN and PNP are the two ...

The first announcement of the invention of the transistor met with almost no fanfare. The integrated circuit was originally thought to be useful only in military applications. The microprocessor's ...

Nanoscale 3D transistors made from ultrathin semiconductor materials can operate more efficiently than silicon-based devices, leveraging quantum mechanical properties to potentially enable ...

After nearly a decade and five major nodes, along with a slew of half-nodes, the semiconductor manufacturing industry will begin transitioning from finFETs to gate-all-around stacked nanosheet ...

Based on the principles above, bipolar transistors can be one of two types: NPN (a p-region sandwiched between two n-regions) or a PNP (the opposite of an NPN). The current and voltage polarities of ...

The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few optical transistors or logic devices possess them 3.
