摘要： Methods are provided for base capacitance compensation of traces in a touchpad sensor. Compensation areas are calculated by evaluating the differences between the base capacitances of the traces, or the differences between the base capacitances of the traces and a target value. The compensation areas are electrically connected to respective traces to equalize the base capacitances of the traces. Alternatively, a relationship between the areas of the traces and the distances from the traces to a grounding layer for equalizing the base capacitances of the traces is derived and from which the areas of the traces or the position of the grounding layer are adjusted.
