  • Magnetic field sensor and apparatus for measuring magnetic field
    Patent number: 10466313
    Abstract: A magnetic field sensor of the present invention includes a first electrode including a magnetic material, a second electrode including a non-magnetic material, a common electrode disposed between the first electrode and the second electrode and connected to a ground terminal, a power supplier of which one end is connected to the first electrode and the second electrode and of which another end is connected to the common electrode to supply power of a frequency band required, a variable resistor configured to control at least one of a resistance value between the first electrode and the power supplier or a resistance value between the second electrode and the power supplier, and a differential amplifier connected to the first electrode through a positive terminal and connected to the second electrode through a negative terminal to output a difference value between a first capacitance generated by the first electrode and a second capacitance generated by the second electrode in response to external application
    Type: Grant
    Filed: November 18, 2015
    Date of Patent: November 5, 2019
    Assignee: KOREA RESEARCH INSTITUTE OF STANDARDS AND SCIENCE
    Inventors: Wan-Seop Kim, Po Gyu Park, Young Gyun Kim, Mun Seog Kim, Dan Bee Kim, Sung Jung Joo
