The MOSFET in Figure 1 is used as both a heater and a temperature sensor in a thermostatic circuit. Figure 1 Circuit diagram for using a MOSFET as a thermostatic heater. The circuit can be used as a ...

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 . . .

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 ...

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 ...

We like to pretend that our circuit elements are perfect because, honestly, it makes life easier and it often doesn’t matter much in practice. For a normal design, the fact that a foot of wire has a ...

The ever-shrinking features of transistors etched in silicon have always required pushing the cutting edge of manufacturing technology. The discovery of atomically thin materials like graphene and ...

Your beloved pooch has a tendency to run off. It’s time to pay a visit to the vet to get her microchipped. On the morning of your appointment, the alarm on your smartphone wakes you up. The house is ...
