An improved on-chip type filter for filtrating electromagnetic noise is disclosed. Within a sensor chip are provided processing and amplifying circuits, a ground pad, a power pad and an output pad. Also, within the sensor chip are disposed low pass filters between the power pad, the outpad and the circuits to filtrate electromagnetic noise. The lengths of aluminum wires connecting the power pad, the output pad and the low pass filters are shorter than the lengths of aluminum wires connecting the ground pad and the low pass filters. The aluminum wires connecting the power pad or the output pad and the low pass filters are uncrossed wires, which do not cross any other wires. |
