The present disclosure describes techniques for detecting foreign objects. In some aspects, an apparatus for detecting objects is provided. The apparatus includes a plurality of sense circuits, each of the plurality of sense circuits including a primary sense coil having a first terminal and a second terminal, a secondary sense coil having a first terminal and a second terminal, and a capacitor having a first terminal and a second terminal. The first terminal of the capacitor is electrically connected to the second terminals of each of the primary sense coil and the secondary sense coil. The apparatus further includes a driver circuit electrically connected to the first terminal of the primary sense coil of each of the plurality of sense circuits. The apparatus further includes a measurement circuit electrically connected to the first terminal of the secondary sense coil of each of the plurality of sense circuits.
