In the simple circuit shown, an LED with current limiting resistor will light when a magnet is brought close to the HES. If it does not, try reversing the pole. The opposite side of the sensor will ...

Autozero circuit that allows the user to automatically adjust the zero-point virtual ground terminal of the scope with the ...

You can use a current-shunt or Hall-effect sensor to make such measurements, ... Figure 1 shows the TMCS1123 block diagram, ... or other high-voltage circuit topologies.
