According to one embodiment, the pair of semiconductor regions are provided respectively on a pair of side walls of the second semiconductor layer having the fin configuration to form tunnel junctions with the second semiconductor layer. One example regulated power converter includes a an energy transfer element coupled between a power converter input and first and second power converter outputs. The sub-edges conduct in parallel with virtually zero power dissipation. The invention further relates to a device for the application of a chip module to an antenna module.
