Abstract
According to one embodiment, an electronic device includes at least one variable capacitor including a first electrode and a second electrode, and being brought into one of a first state and a second state according to a voltage applied between the first electrode and the second electrode, the first electrode and the second electrode being closer to each other in the second state compared with in the first state, and a charge pump circuit provided in a first integrated circuit chip and producing a voltage for establishing the second state. An external capacitor is connectable to the first integrated circuit chip and is receivable the voltage produced by the charge pump circuit.
