METHOD AND SYSTEM FOR DETERMINING A CAPACITANCE VALUE
A method for determining a capacitance value of a capacitor is provided. The method includes receiving a current signal flowing through the capacitor and receiving a voltage signal applied across the capacitor. The received voltage signal and the received current signal are filtered with a low pass filter. The filtered voltage signal and the filtered current signal are then discretized. The discretized voltage signal and the discretized current signal are transformed into a frequency domain. The capacitance value of the capacitor is determined from the transformed voltage signal and the transformed current signal.
Detection circuit
A detection circuit for detecting an external device with a specific resistance is provided. The detection circuit includes a first resistor, a second resistor, a first converter, a second converter, a device converter, a first current comparator, and a second current comparator. The first resistor has a first resistance. The second resistor has a second resistance. The first converter is configured to convert the first resistance into a first current. The second converter is configured to convert the second resistance into a second current. The device converter is configured to convert the specific resistance into a specific current. The first current comparator is configured to compare the specific current with the first current, and generate a first output signal. The second current comparator is configured to compare the specific current with the second current, and generate a second output signal.
Circuit for measuring power violations using high side current sensing
A power monitoring circuit and method for detecting deviations in the output of a power supply. The power monitor is configured to detect and measure two different types of deviations: transient deviations short surges or spikes in the current drawn by the device being powered and prolonged deviations over a threshold current that may be intentional, temporary increases in the output of the power supply. The power monitor collects information such as the number of each type of deviation, the duration of each deviation and the peak current describing identified deviations. This collected information can then be used, especially during the development phase, to locate the root cause of the deviation. The components of the power monitor used to detect and measure these deviations may be disabled and enabled as needed.
Method of manufacturing semiconductor device, and probe card
Reliability of an electrical test of a semiconductor wafer is improved. A method of manufacturing a semiconductor device includes a step of performing an electrical test of a semiconductor element by allowing contact portions (tips) of a force terminal (contact terminal) and a sense terminal (contact terminal) held by a probe card (first card) to come into contact with an electrode terminal of a semiconductor wafer. In the step of performing the electrical test, the contact portions of the force terminal and the sense terminal move in a direction away from each other after coming into contact with the first electrode terminal.

HVMOS Reliability Evaluation using Bulk Resistances as Indices
A method of determining the reliability of a high-voltage PMOS (HVPMOS) device includes determining a bulk resistance of the HVPMOS device, and evaluating the reliability of the HVPMOS device based on the bulk resistance.
METHOD AND PROTECTION DEVICE FOR GENERATING AN ERROR SIGNAL INDICATING AN ERROR TYPE OF AN ERROR IN A MULTI-PHASE ELECTRICAL ENERGY SUPPLY NETWORK
A method for generating an error signal indicating an error type of an error in a multi-phase electrical energy supply network. Measured values describe a current operating state of the network. The measured values are transmitted to a protection device. An evaluating device evaluates every possible loop of the network that can be affected with respect to the recognition of the error type of an error, by using the measured values. In order to be able to more reliably recognize the error type even under different network conditions, the measured values and/or values derived from the measured values are evaluated using at least two different protection criteria, for every possible loop. Each of the protection criteria is suitable for indicating an error type of an error present in the evaluated loop, and the error signal is generated in consideration of all available evaluation results of the protection criteria.
