Negative voltage sources are widely used in various applications such as computing systems, liquid-crystal display (LCD) source drivers and audio amplifiers. Using the additional secondary winding of ...

It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...

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 ...

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, ...
