Abstract:
1. A capacitor device having a plurality of capacitances, the capacitor device comprising: a substrate including a first well and a second well, the first well having a first conductivity type and having a first voltage applied thereto, and the second well having a second conductivity type and having a second voltage applied thereto; and a plurality of gate electrodes including at least one first gate electrode and at least one second electrode, the at least one first gate electrode disposed on an upper portion of the first well such that the at least one first gate electrode is insulated from the first well, and the at least second gate electrode disposed on an upper portion of the second well such that the at least one second gate electrode is insulated from the second well, wherein the plurality of capacitances includes a first capacitance, a second capacitance, and a third capacitance, the first capacitance being between the first well and the second well, the second capacitance being between the first well or the second well and the gate electrode, and the third capacitance being between the at least one first gate electrode and the at least one second gate electrode.
