摘要： A packaged current sensor includes a lead frame, an integrated circuit, an isolation spacer, a first magnetic concentrator, and a second magnetic concentrator. The lead frame includes a conductor. The isolation spacer is between the lead frame and the integrated circuit. The first magnetic concentrator is aligned with the conductor. The second magnetic concentrator is aligned with the conductor.

摘要： A Hall sensor circuit includes a first Hall sensor, a second Hall sensor, a first preamplifier circuit, a second preamplifier circuit, a subtractor circuit, and a duty cycling circuit. The first preamplifier circuit includes an input and an output. The input is coupled to the first Hall sensor. The second preamplifier circuit includes a first input, a second input, and an output. The first input is coupled to the second Hall sensor. The subtractor circuit includes a first input coupled to the output of the first preamplifier circuit, a second input coupled to the output of the second preamplifier circuit, and an output coupled to the second input of the second preamplifier circuit. The duty cycling circuit is coupled to the second preamplifier circuit and the second Hall sensor.

摘要： A structure includes a substrate which includes a surface. The structure also includes a horizontal-type Hall sensor positioned within the substrate and below the surface of the substrate. The structure further includes a patterned magnetic concentrator positioned above the surface of the substrate, and a protective overcoat layer positioned above the magnetic concentrator.

摘要： An integrated filter optical package including an ambient light sensor that incorporates an infrared (IR) filter in an integrated circuit (IC) stacked-die configuration is provided. The integrated filter optical package incorporates an infrared (IR) coated glass layer to filter out or block IR light while allowing visible (ambient) light to pass through to a light sensitive die having a light sensor. The ambient light sensor detects an amount of visible light that passes through the IR coated glass layer and adjusts a brightness or intensity of a display screen on an electronic device accordingly so that the display screen is readable.
