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 ...

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.

In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil ...

A transistor – a word blend of "transfer" and "resistor" – is a fundamental component of today's advanced electronics. Essentially, a transistor, as one of the foundational elements of modern ...

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.

CMOS technology combines two types of transistors that work together, leading to efficient power use and high noise immunity. CMOS technology uses two different types of transistors, n-type (nMOS) and ...

After an exhaustive review of suspect transistors in NASA's Europa Clipper spacecraft, NASA managers have cleared the probe for launch next month as planned on a $5.2 billion mission to find out ...

Darlington transistors are circuits that combine two bipolar transistors in a single device. They provide high current gain and require less space than configurations that use two discrete transistors ...

Lambang Garuda Pancasila merupakan simbol negara bangsa Indonesia. Di samping itu, Pancasila adalah dasar negara Republik Indonesia dan menjadi pedoman hidup masyarakat dalam berbangsa dan ...

Tidak banyak yang tahu perancang lambang Garuda Pancasila. Namanya dilupakan karena dianggap terlibat upaya kudeta Westerling 1950. Kini ada upaya untuk membersihkan namanya. Sejarah seringkali ...
