Abstract
A symmetrical capacitor includes at least a first metal layer and a second metal layer. Each of the metal layers has a first electrode plate and a second electrode plate separated by a predetermined distance. The first electrode plates on the metal layers are symmetrical, and the second electrode plates on the metal layers are symmetrical. Given the symmetrical structure of the capacitor, the output ports of the capacitor have the same electrical features. Therefore, there will not be a direction problem when the capacitor is used, and the symmetrical electrical features are improved.
