Abstract
A Digitiser includes grid of conductors including excitation conductors and detection conductors; excitation circuitry for applying signals to selected excitation conductors; measurement circuitry for obtaining measurements from selected detection conductors; and processing circuitry to detect one or more objects positioned adjacent the grid of conductors. The excitation circuitry operates in a cyclic manner to select each of the excitation conductors during an excitation cycle, wherein an excitation cycle includes a sequence of excitation intervals during each of which a different pair of neighbouring excitation conductors is selected by the excitation circuitry and to which complementary excitation signals are applied. Double differential measurement for a selected pairs of excitation and detection conductors is obtained. A method of making a transducer making use of various adhesive layers and ultrasonic bonding is also present.
