Latest Patents
Namiki's latest patents include a magnetic sensor utilizing integrated silicon Hall effect elements. This invention features two Hall effect devices formed on a silicon single crystal substrate, which are series-connected to create a magnetic sensor. Each device has a pair of drive electrodes that are spaced apart and held at different potentials to drive the Hall effect device. The design allows for the development of a Hall voltage when exposed to an external magnetic field. A comparator is employed to compare the potentials of two selected Hall terminals from different Hall devices, producing a compared signal. Additionally, a switching element is connected to one of the Hall devices to control the potential of the Hall terminals, ensuring equalization in response to the compared signal. This innovative approach results in a totalized Hall voltage from the two Hall effect devices.
