摘要： A non-linear Hall IC that stores conversion information for converting Hall voltage output from a Hall element, and converts the Hall voltage into an output voltage based on the conversion information stored. The Hall voltage is converted into the output voltage such that a relation between the magnetic field strength and the output voltage becomes a non-linear relation.

The Hall sensor has an electric current input for providing a Hall sensor output signal depending on a magnetic field acting on the Hall sensor and depending on the electric current. The processing device is arranged for receiving an input signal including the Hall sensor output signal and processing the input signal to provide an output signal associated with the Hall sensor output signal.

摘要： A magnetic field sensor for measurement of the three components (Bx, By, Bz) of a magnetic field comprises a Hall-effect element (1) and an electronic circuit (22). The Hall-effect element (1) comprises an active area (18) of a first conductivity type which is contacted with voltage and current contacts (2-5 or 6-9). Four voltage contacts (2-5) are present which are connected to inputs of the electronic circuit (22). By means of summation or differential formation of the electrical potentials (V2, V3, V4, V5) present at the voltage contacts (2-5), the electronic circuit (22) derives three signals (Vx, Vy, Vz) which are proportional to the three components (Bx, By, Bz) of the magnetic field.

摘要： A constant input impedance AC coupling circuit for a current probe measurement system has a resistive-capacitive network that includes a capacitor for coupling the current output signal of a current measurement probe to the low input impedance measurement instrument and the resistive terminating element disposed in the measurement instrument. The resistive-inductive network includes a resistor and a synthesized inductor having a high inductive value, large current carrying capacity and an L/R time constant equal to the RC time constant of the resistive capacitive network. The resistive-inductive network is coupled to the resistive-capacitive network and receives the current output signal from the current measurement probe for terminating DC and low frequency signal components of the current output signal below the low frequency cutoff of the resistive-capacitive network in the same low input impedance of the measurement instrument.

摘要： The present invention provides a magnetic sensor with a simple configuration which detects a magnetic field strength of both polarities and which consumes a small amount of power. The magnetic field sensor of the present invention comprises a first switch part which inputs a signal outputted from a magnetoelectric element which outputs a signal corresponding to an applied magnetic field, and which outputs a signal, switching so that a polarity during a first period and a fourth period and a polarity during a second period and a third period are mutually opposite; an amplifier which amplifies an output signal of the first switch part and outputs a signal to its output terminal pair; a memory element, both ends of which are connected to the output terminal pair of the amplifier, and which holds a voltage outputted from the amplifier; a second switch part which is inserted and makes a connection between one of the output terminal and one terminal of the memory element, and which closes during the first period and the third period and opens during the second period and the fourth period; and a switch output terminal which outputs an output signal of a first polarity of the second switch part during the second period, and which outputs an output signal of a second polarity of the second switch part during the fourth period.

摘要： A Hall effect sensor and capacitor assembly includes leadless chip type capacitors employed as EMI shielding/ESD protection and bypass capacitors. In a first embodiment, a molded carrier structure provides a housing for mounting a Hall cell element as well as one or more EMI shielding or bypass capacitors. The carrier housing facilitates interconnection of the Hall cell and the chip capacitor. Additionally, this structure simplifies the manufacturing process for connection of the smaller leadless chip capacitor components. In an alternate embodiment, an insulated, molded encapsulation is applied and surrounds the chip capacitors and the connections to the Hall effect sensor leads.

摘要： A fully packaged current monitor system for galvanically isolated current measurement is manufactured in line with commercial IC fabrication and LOC packaging technology. A current path is part of the lead frame on which a die with sensor means is mounted with the aid of an electrically insulating correspondingly pre-patterned glue tape, the structured surface of the die facing the lead frame. The system manufactured in this way achieves for currents up to +/−10 A, a system accuracy of better than 50 mA and is applicable for currents up to the order of 50 A. The system performance can be further improved by ferromagnetic field concentrators and on-chip compensation techniques.
