Offset and low frequency noise insensitive magnetic sensor |
摘要 |
The invention provides an offset and low frequency noise insensitive magnetic sensor which incorporates a magnetic field effect transistors (MagFETs). Methods of improving the signal to noise ratio and reducing errors from offsets when measuring magnetic fields using MagFETs are also described. The invention also provides for the use of such methods and sensor in circuitry adapted to provide for residual current detection
