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, ...

Some circuits need a negative supply voltage that only has to supply a small current. Providing a separate transformer winding for this (possibly even with a rectifier and filter capacitor) would be a ...

When [Nicole Express] got her hands on the logic board for the 1986 SNK arcade game Athena, she ran into a rather thorny problem: The board expected to be fed negative five volts! [Nicole]’s analysis ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...

Low voltage amplifiers are often used in single-supply voltage circuits and make use of the rail-to-rail output feature these amplifiers have. While the output of these amplifiers can swing close to ...

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, ...
