(Note: In the figure, while it is common to draw positive rails at the bottom of circuits in schematic diagrams and, based on it, negative buck topologies show ground (most positive rail) on the top ...

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 ...

Negative feedback is a universal control mechanism that lets a system's output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it ...

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 ...
