ABSTRACT:
A circuit for sensing a current includes a first upper resistor having a first end coupled to a first end of a sense resistor, the sense resistor being configured to receive an input current. A second upper resistor has a first end coupled to a second end of the sense resistor, so that the sense resistor defines a first potential between the first and second ends of the sense resistor. A first lower resistor is provided between the first upper resistor and the ground. A second lower resistor is provided between the second upper resistor and the ground. An amplifier has a first input node and a second input node, the first input node being coupled to a node between the first upper resistor and the first lower resistor. The second input node is coupled to a node between the to the second upper resistor and the second lower resistor. The first and second input nodes defines a second potential corresponding to the first potential.
