Abstract
A charge pump has a reference stage that simulates the output stage of the paths, at least in terms of the output-side transistors of the paths. An equivalent symmetrical current is generated on a reference stage. The equivalent symmetrical current replicates the fault current and controls a device for regulating the second path.
