A position sensor for determining the position of a target includes a center-tapped transmit coil with three terminals: a first terminal, a center-tap, and a second terminal. The sensor has a transmitter that applies an oscillating signal across the first and second terminals of the transmit coil. A receiver is connected to the first terminal, second terminal, and center-tap of the transmit coil. The processing circuit calculates the target's position by applying a transformation to the signals received from the three terminals.
