Abstract:
1. A device for converting a current sensing voltage to an adjusted current sensing voltage, the device comprising: a matching component sharing physical characteristics with a current sensing component at which the current sensing voltage is sensed, the matching component having a resistance associated with a resistance of the current sensing component, the matching component coupled to receive a reference current; a first voltage divider unit coupled to sense a voltage corresponding to the matching component resistance and the reference current, the first voltage divider unit comprising a first voltage dividing component and a second voltage dividing component; a second voltage divider unit coupled to sense the current sensing voltage, the second voltage divider unit comprising a first voltage dividing component and a second voltage dividing component; and a feedback unit having an output coupled to a control input of the first voltage dividing components, the second voltage divider unit having an output providing the adjusted current sensing voltage.
