| 摘要 |
In some embodiments, the arrangement includes a sense element to convey a current from a source to a load and a compensation element located proximate to the sense element. The compensation element has a resistance that changes proportional to a change in temperature of the sense element. In several embodiments, the arrangement further includes an operational amplifier having a first input connected to the sense element, a second input connected to the compensation element and an output that provides an output signal that biases a current through the compensation element in response to a voltage across the sense element. In such embodiments, the bias current provides an output signal proportional to the conveyed current and the compensation element provides temperature compensation for the output signal. Other embodiments are also disclosed.
