According to an embodiment, an optical MEMS transducer includes a diffraction structure including alternating first reflective elements and openings arranged in a first plane, a reflection structure including second reflective elements and configured to deflect with respect to the diffraction structure, and an optical element configured to direct a first optical signal at the diffraction structure and the reflection structure and to receive a second optical signal from the diffraction structure and the reflection structure. The second reflective elements are arranged in the first plane when the reflection structure is at rest. Other embodiments include corresponding systems and apparatus, each configured to perform various embodiment methods.

System and method for an optical MEMS transducer

An electronic device includes a substrate, an insulating layer arranged on the substrate, the insulating layer having an opening in an area of the surface of the substrate, an active layer arranged within the opening on the surface of the substrate, the active layer including a guard ring in those areas of the surface and of the active layer which are adjacent to the insulating layer, and a contacting layer arranged on an area of the active layer, the contact layer being adjacent to an area of the guard ring. The device may be produced by a process of three-fold self-alignment, to be precise utilizing a spacer process by means of which a diffusion source having a lateral extension far below the lithography limit is made possible.

Electronic device with guard ring

The magnetic component uses at least two different layers of magnetic material for carrying and amplifying the magnetic flux. The use of two different layers which may, however, have the same material composition allows the magnetic conductors to form a magnetic circuit with a locally matched domain alignment. The magnetic component accordingly allows considerable improvements to be achieved in the component parameter, in particular a considerable increase in the Q-factor.

Magnetic component

A conductor network includes trimming capacitors and is connected in parallel with a resonant circuit. The trimming capacitors can be connected in parallel with the variable-capacitance diodes in the resonant circuit through PIN diodes, enabling trimming of the resonant circuit.
