Abstract
A measurement circuit for a sensor, the measurement circuit includes at least one detection branch including at least a first series of at least one dipole and a second series of at least one dipole, the series being connected in parallel and connected at their inputs to a common input terminal, each series of dipole being connected to a distinct output terminal, and an electronic circuit including a bias circuit configured to apply a bias current to the detection branch from the input terminal, and a read circuit configured to impose on each output terminal the same potential referred to as the 'reference potential' (V); the electronic circuit including a determination circuit for determining variations in impedances of each series of dipole of the detection branch on the basis of the current applied to each output terminal by the read circuit so as to keep the potentials equal.
