Abstract: A magnetic field sensor is disclosed for providing an output signal in response to an external magnetic field. The sensor comprises a primary magnetic field transducer for producing a primary signal in response to the external magnetic field and having a first magnetic field saturation characteristic; a secondary magnetic field transducer for producing a secondary signal in response to the external magnetic field and having a second magnetic field saturation characteristic. The first magnetic field saturation characteristic is different from the second magnetic field saturation characteristic. The sensor is configured to use the secondary signal to correct for errors in the output signal arising from saturation of the primary transducer.

Abstract: A MEMS device, such as a microphone, uses a perforated plate. The plate comprises an array of holes across the plate area. The plate has an area formed as a grid of polygonal cells, wherein each cell comprises a line of material following a path around the polygon thereby defining an opening in the center. In one aspect, the line of material forms a path along each side of the polygon which forms a track which extends at least once inwardly from the polygon perimeter towards the center of the polygon and back outwardly to the polygon perimeter. This defines a meandering hexagon side wall, which functions as a local spring suspension.

Abstract: A read out circuit for a sensor uses a feedback loop to bias the sensor to a desired operating point, such as the maximal possible sensitivity, but without the problem of an instable sensor position as known for the conventional read-out with constant charge. The reference bias to which the circuit is controlled is also varied using feedback control, but with a slower response than the main bias control feedback loop.

Abstract: The invention provides a method of forming an electric field gap device, such as a lateral field emission ESD protection structure, in which a cathode layer is formed between dielectric layers. Anode channels are formed and they are lined with a sacrificial dielectric layer. Conductive anode pillars are formed in the anode channels, and then the sacrificial dielectric layer is etched away in the vicinity of the anode pillars. The etching leaves a suspended portion of the cathode layer which defines a lateral gap to an adjacent anode pillar. This portion has a sharp end face defined by the corners of the cathode layer and the lateral gap can be defined accurately as it corresponds to the thickness of the sacrificial dielectric layer.

Abstract: Embodiments of a method for forming a field emission diode for an electrostatic discharge device include forming a first electrode, a sacrificial layer, and a second electrode. The sacrificial layer separates the first and second electrodes. The method further includes forming a cavity between the first and second electrode by removing the sacrificial layer. The cavity separates the first and second electrodes. The method further includes depositing an electron emission material on at least one of the first and second electrodes through at least one access hole after formation of the first and second electrodes. The access hole is located remotely from a location of electron emission on the first and second electrode.
