There comes a time in every hardware hacker’s career during which they first realize they need a negative voltage rail in their project. There also comes a time, usually ~10ms after realizing this, ...

If we say that a hacker is somebody who looks at a “solved” problem and can still come up with multiple alternative solutions, then [Charles Ouweland] absolutely meets the grade. Not that we needed ...

There are standard techniques to generate negative output voltages, and there are well-known approaches to dynamically adjust an output voltage. The missing link that I hope to address in this article ...

Negative voltage sources are widely used in various applications such as computing systems, liquid-crystal display (LCD) source drivers and audio amplifiers Zach Zhang, Staff Applications Engineer, ...

The lowest-cost way to achieve this goal is to use a 1-quadrant unipolar dc supply (Fig. 1a) outfitted with a polarity reversal relay. However, using a polarity reversal relay brings with it three ...
