Abstract
Transistor devices are provided. In some example implementations, a magnetic field sensor chip is fitted on a load electrode of a transistor chip. In other example implementations, two magnetic field sensors are arranged on a load electrode of a transistor chip in such a way that they measure different effective magnetic fields in the event of current flow through the transistor chip.
