Abstract: A magnetic secure transmission (MST) device which generates an MST signal includes a first transmitter, a first coil that generates a first signal depending on an operation of the first transmitter, a second transmitter that operates at an operating frequency of the first transmitter, and a second coil that generates a second signal for offsetting or compensating for the first signal depending on an operation of the second transmitter. The MST signal is generated as the first signal and the second signal overlap each other.

Abstract: A battery device includes a first battery and a second battery connected in series. An electronic device for determining a state of charge of the battery device includes a sense resistor connected in series to the second battery, and a fuel gauge. The fuel gauge is configured to determine the state of charge of the battery device based on a first terminal voltage of the first battery, a first calculation current of the first battery, a second terminal voltage of the second battery, and a measurement current of the second battery measured through the sense resistor. The fuel gauge calculates a second calculation current of the second battery using a battery parameter of an equivalent circuit model, corrects the battery parameter when a difference between the measurement current and the second calculation current is not less than a threshold value, and calculates the first calculation current using the battery parameter or a corrected battery parameter.
