    摘要: A method of calibrating a magnetic field sensor includes setting a first input signal at a first input node of a processor of the magnetic field sensor to a constant value. While the magnetic field sensor experiences a magnetic field, a first transition at an output node of the processor is measured. A second input signal at a second input node of the processor is set to the constant value. While the magnetic field sensor experiences the magnetic field, a second transition of at the output node of the processor is measured. An orthogonality error value is calculated based on a deviation of the first transition and the second transition. The first and/or second input signal is adjusted by modifying the first and/or second input signal by a function of the calculated orthogonality error value to compensate for the orthogonality error.

    摘要: Automatic test equipment with multiple components to generate highly accurate and stable analog test signals and method for operating the test system in semiconductor manufacturing process are disclosed. Output analog signals from existing test systems often fail the stability and accuracy requirement with less than 10 mV variations for testing certain electronic devices, due in part to environmental condition variations such as temperature fluctuations. Traditional compensation mechanisms for temperature variations involve time consuming and disruptive calibration procedures. Disclosed here is a system and method that provides near real-time monitoring and compensation for temperature-induced variations via a digital control mechanism that compensates for environmental variations in a time scale of less than 10 milliseconds and maintains the AC output analog signal with 10 milliVolt accuracy.

    摘要: The invention concerns devices and methods for calibrating an Automated Test Equipment (102) for automated testing of a Device Under Test. According to an aspect of the invention, the method comprises providing at least two digital channel signals (501, 502) by at least two different channels (601, 602) of the Automated Test Equipment (102), wherein the digital channel signals (501, 502) comprise, except for a possible time shift relative to each other, an identical or a complementary pattern with respect to their edges (301, 302). The method further comprises sum-combining or difference-combining the at least two digital channel signals (501, 502) in order to obtain a combined residual signal (607). The step of combining is performed such that the combining provides a combined residual signal (607) without a time-variant component (609) if the at least two digital channel signals (501, 502) have a predetermined time shift (τ) or a predetermined phase shift (Δρ) relative to each other, or such that the combined residual signal (607) comprises a time variant component (609) if the two digital channel signals (501, 502) have a time shift different from the predetermined time shift or a phase shift different from the predetermined phase shift. The method further comprises measuring the combined residual signal (607) and determining a relative timing of the at least two digital channel signals (501, 502) relative to each other on the basis of the measurement of the combined residual signal (607).
