Abstract: A base carries a first chip and a second chip oriented differently with respect to the base and packaged in a package. Each chip integrates an antenna and a magnetic via. A magnetic coupling path connects the chips, forming a magnetic circuit that enables transfer of signals and power between the chips even if the magnetic path is interrupted, and is formed by a first stretch coupled between the first magnetic-coupling element of the first chip and the first magnetic-coupling element of the second chip, and a second stretch coupled between the second magnetic-coupling element of the first chip and the second magnetic-coupling element of the second chip. The first stretch has a parallel portion extending parallel to the faces of the base. The first and second stretches have respective transverse portions extending on the main surfaces of the second chip, transverse to the parallel portion.

Abstract: An inertial sensor having a body with an excitation coil and a first sensing coil extending along a first axis. A suspended mass includes a magnetic-field concentrator, in a position corresponding to the excitation coil, and configured for displacing by inertia in a plane along the first axis. A supply and sensing circuit is electrically coupled to the excitation coil and to the first sensing coil, and is configured for generating a time-variable flow of electric current that flows in the excitation coil so as to generate a magnetic field that interacts with the magnetic-field concentrator to induce a voltage/current in the sensing coil. The integrated circuit is configured for measuring a value of the voltage/current induced in the first sensing coil so as to detect a quantity associated to the displacement of the suspended mass along the first axis.

Abstract: Embodiments are directed to electrically confined ballistic devices, circuits, and networks. One such device includes a heterostructure that has a first semiconductor layer, a second semiconductor layer, and a two-dimensional electrode gas (2DEG) layer between the first and second semiconductor layers. The device further includes an input electrode electrically coupled to the 2DEG layer and an output electrode electrically coupled to the 2DEG layer. A first confinement electrode is positioned on the heterostructure. The first confinement electrode, in use, generates first space charge regions which at least partially define a boundary of the ballistic device within the 2DEG layer between the input electrode and the output electrode in response to a first voltage.

Abstract: A device includes a particle propagation channel, a particle deflector, a particle source, and a particle sink. The particle deflector facilitates ballistic transport of particles from a particle inflow portion through a particle flow deflection portion to a particle outflow portion. The particle deflector is arranged at the particle flow deflection portion and is activatable to deflect particles in the flow deflection portion and is configured to selectively prevent the particles from reaching the particle outflow portion. The particle source and particle sink are configured to cause a current path of the particles through the device.
