A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...

This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the ...

Ever wondered how a solar-powered lamp powers an LED with just a single 1.2 V cell? A closer look reveals a clever single-transistor voltage converter circuit. Curious how a solar-powered lamp powers ...

Abstract: This paper surveys the history of the electric-circuit representation of the transistor over the past fifty years. During the first two decades after the transistor was announced in 1948, ...

Need to switch something on or off using a microcontroller? Using a transistor is one of the best ways to do this, but how exactly do you design properly for transistor switching? [Ben Krasnow] put ...

46 IN-CIRCUIT TRANSISTOR TESTER by A. Rigby In electronic troubleshooting a transistor is generally not above suspicion until it responds correctly to the usual diode-tests with an ohmmeter. Before ...

This chapter explains how we use transistors, how we bias them, so they generate working and useful circuits, and how we stabilize them as the temperature, currents, and applications vary. There are ...

MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable ...

A new magnetic transistor switches current ten times more strongly than silicon chips while operating at lower energy, and ...

In the half-century since the transistor was invented, this workhorse component of almost every electronic device has shrunk from the size of a pencil eraser to smaller than a bacterium. The ...
