Abstract
A fingerprint sensing device comprises a substrate and an array of sensor cells formed over the substrate. The sensor cells are divided into multiple groups. Each group is associated with a group-identifiable signal. The sensor cells in each group are configured to transmit the group-identifiable signal of the respective group and are further configured to simultaneously receive the group-identifiable signals transmitted by the sensor cells in other groups. The group-identifiable signals are orthogonal with respect to each other.
