Hall effect device and magnetic coil circuits for magnetic field detection |
摘要 |
Magnetic field sensing circuits including wire coils and Hall effect devices are provided which produce high-gain output for a relatively low change in perceived field intensity. Series connected plural Hall effect devices are connected to the coil and include amplifier and integrator circuits interposed at selected points between Hall effect devices to modify the output signal gain and passband. The circuits may include diode and capacitance elements to modify the circuit output signal.
