Abstract
A sensor operates to produce a differential signal with a voltage regulated that generates a regulated voltage to a first sensor element for detecting a physical parameter. A current mirror circuit is configured to provide a first sensor current to the first sensor element, detect the first sensor current at the first sensor element and duplicate the detected current to provide a second sensor current to a second sensor element. The second sensor element detects the physical quantity with the replicated current.
