Abstract: A magnetoresistance element structure disposed parallel to an x-y plane defined by an x-axis and a y-axis orthogonal to the x-axis can include a first magnetoresistance element having a plurality of first shapes coupled in series to result in the first magnetoresistance element having a first serpentine shape parallel to the x-y plane; and a second magnetoresistance element having a plurality of second shapes coupled in series to result in the second magnetoresistance element having a second serpentine shape parallel to the x-y plane, wherein the plurality of first shapes and the plurality of second shapes are disposed in an interdigitated pattern. A magnetic field sensor can use the above magnetoresistance element structure. Nested magnetoresistance elements and magnetic field sensors are also described.

Abstract: In one aspect, an integrated circuit (IC) includes an output port enabling measurement of a performance characteristic of the IC at a first temperature. The performance characteristic of the IC is a minimum value at the first temperature with respect to any other temperature. The first temperature may be room temperature.

Abstract: A monitor circuit for monitoring a level of a first and second regulated source may monitor a voltage level of regulated voltages or a current level of regulated currents. In an embodiment, the monitor circuit includes circuitry responsive to a first regulated voltage and to a second regulated voltage. A first circuit responsive to the first regulated voltage and to the second regulated voltage generates a first error signal indicative of at least one of an overvoltage condition of the first regulated voltage and an undervoltage condition of the second regulated voltage. A second circuit responsive to the first regulated voltage and to the second regulated voltage generates a second error signal indicative of at least one of an undervoltage condition of the first regulated voltage and an overvoltage condition of the second regulated voltage. A method for monitoring the levels of first and second regulated sources is also provided.
