Abstract
A sensor system for measuring a physical quantity includes: a bridge sensor having at least two terminal pairs, a current source for applying a bias current between the bias terminal pair, resulting in a differential sensor signal on a readout terminal pair, wherein the differential sensor signal is indicative for the physical quantity, and an amplifier comprising a first input node and a second input node for receiving the differential signal and at least one output node, wherein the amplifier is configured for amplifying the differential sensor signal and putting the resulting signal on the at least one output node, wherein the sensor system is configured such that, in operation, the amplifier is powered by at least part of the bias current.
