In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

From lighting bulbs to mastering Kirchhoff’s Rules, AC/DC electronics labs bring theory to life. These hands-on experiments teach real-world electrical skills using resistors, capacitors, diodes, and ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the ...

Properly selected components make it easier to design modern, energy-efficient power supplies. In this article we present an ...

Logical circuits have been built from nanosheet stacks of various transistors, which could make electronic devices faster and more compact. Xiong Xiong is in the School of Integrated Circuits and the ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

In previous parts of this series we reviewed the basic transistor parameters that determine ac voltage gain and practical considerations limiting high gain. The role of a coupling capacitor was ...
