The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...

Every non-battery-powered electronic device requires converting offline ac power to some dc voltage for powering electronics. Nowadays, efficient conversion of electrical power is becoming an ...

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 ...

Researchers previously reported a self-aligned technique for making graphene transistors with unparalleled speed, but scalability was a question. The team now uses a dielectrophoresis assembly ...

Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel ...

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 ...

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

Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But ...
