Abstract: The present invention relates to an electronic device and a method for controlling a charging operation of a battery. The charging control method includes charging a battery using a first charging mode, if a current voltage of the charged battery coincides with a predetermined voltage, decreasing an intensity level of a charging current and charging the battery using the decreased charging current intensity, and if the decreased charging current intensity coincides with a predetermined current intensity, converting from the first charging mode to a second charging mode and charging the battery using the second charging mode.

Abstract: A discrete capacitance switching circuit includes a DC decoupling capacitor connected between a power node that receives an AC signal and a first node, a diode connected between the first node and a second node, a unit capacitor connected between the second node and a reference node that receives a ground voltage, and a bias circuit. The bias circuit is configured to apply a first DC voltage to the first node and apply a second DC voltage to the second node. The applied first and second DC voltages control a switching operation of the diode.
