Analysis of a NIC as a temperature compensator for bridge sensors

In this communication we will show an in depth analysis of a Negative Impedance Converter (NIC) as temperature compensation device for bridge sensors. Even though its use has been proposed in some application notes, no theoretical justification has been reported so far, at least to the best of our knowledge. This paper attempts to fill this gap, giving closed form expressions for a correct use of the NIC in any application.
