Abstract: A fingerprint sensing apparatus includes a plurality of fingerprint sensing electrodes, a plurality of data lines respectively sandwiched by a first capacitance-shielding wire and a second capacitance-shielding wire, a fingerprint sensing circuit including a driver circuit with a gain larger than zero or equal to zero. During fingerprint sensing, the fingerprint sensing circuit sends a capacitance-exciting signal to a selected fingerprint sensing electrode, receiving a fingerprint sensing signal from the selected fingerprint sensing electrode, processing the fingerprint sensing signal with the driver circuit into a capacitance-eliminating signal and applying the capacitance-eliminating signal to the first capacitance-shielding wire and the second capacitance-shielding wire respectively. The capacitance between the first/second capacitance-shielding wire and the corresponding data line can be greatly reduced because the voltages at the first/second capacitance-shielding wire have same phase as that of corresponding data line, thus greatly enhance the accuracy of the fingerprint sensing apparatus.

Abstract: An ESD protection circuit includes at least two unidirectional conduction units arranged between an IO node of an integrated circuit and a positive voltage node, where a first connection node is between the at least two unidirectional conduction units; at least two unidirectional conduction units arranged between the IO node and a negative voltage node, where a second connection node is between the at least two unidirectional conduction units; and a voltage tracking circuit. The input of the voltage tracking circuit is electrically connected to the IO node and the output of the voltage tracking circuit is electrically connected to at least one of the first connection end and the second connection end. By reducing the voltage difference between the IO node and the first connection end or between the IO node and the second connection end, the parasite capacitance associated with the unidirectional conduction unit can be reduced.
