Editor’s note: OK designers, pay attention to this series of tutorials for an in-depth understanding of these really useful amplifier architectures that will help you in your designs with a solid and ...

Electronic circuit designs often require power sources with negative output voltages. There are many different ways of producing a negative output voltage from a positive input voltage. One option is ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Switching dc-dc power supplies are prolific in today's consumer electronics. Most applications use an input source that provides a positive dc voltage referenced to system ground. These sources often ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...
