摘要： A method for testing an integrated circuit and an integrated circuit. The integrated circuit has an internal testing structure which may be accessed via an internal test access port and a control bus which is conducted to the outside via control ports, it being possible to switch over between a running mode and a test mode so that, in the test mode, the test access port is accessed via the control ports and the control bus, thus testing the integrated circuit.

摘要： A shunt resistor includes: two measuring terminals for applying a measuring current flowing through the shunt resistor along a main flow direction; slot structures dividing the shunt resistor along the main flow direction to include two side flow areas of respective first widths and a main flow area of a second width; and two calibration terminals connected to the side flow areas. A circuit connected to the measuring terminals is designed to detect, and generate a signal based on, a measuring current flowing through the shunt resistor. A calibration device connected to the calibration terminals is designed to apply a reference voltage or current to the calibration terminals, and ascertain a calibration voltage based on a falling voltage across those terminals. A correction circuit connected to the calibration device and the detection circuit is designed to correct the signal generated by the detection circuit based on the detected calibration voltage.

摘要： A method for correcting non-linearities of an output signal of an electrical component with the aid of a characteristics map that is defined by discrete interpolation points. In this context, the adjacent interpolation points of the characteristics map are ascertained as a function of at least one signal influencing the non-linearities of the output signal. Interpolation is carried out between these interpolation points, and a corresponding correction signal is ascertained as a function of the or each signal by an interpolation. The output signal of the electrical component is corrected as a function of the correction signal. To improve the correction of non-linear transfer characteristics and/or temperature responses of the electrical component, it is proposed that the or each signal for addressing the characteristics map be high-pass filtered, and the correction signal be ascertained as a function of the or each signal by the interpolation and a subsequent low-pass filtering.
