Abstract

The article describes a new approach for current sensing in circuits with high current. Instead of comparing the voltage across a constant sense resistor with a constant reference voltage, a reference voltage is created across a resistor sharing ground with the sense resistor. Then, the actual voltage at ground can vary without destroying the reading,
