    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 packaged semiconductor device includes an IC die having bump features that are coupled to bond pads flip chip attached to a custom LF. The custom LF includes metal structures including metal leads on at least 2 sides, and printed metal providing a printed LF portion including printed metal traces that connect to and extend inward from at least one of the metal leads over the dielectric support material that are coupled to FC pads configured for receiving the bump features including at least some of the printed metal traces coupled to the bond pads on the IC die. The IC die is flip chip mounted on the printed LF portion so that the bump features are connected to the FC pads.
