Electronic devices including circuits configured to adjust peak intensity of current

A method of operating an electronic device, the method comprising:

• generating, by a driver, a plurality of driving signals based on data and a control signal;
• providing, by a plurality of switches, paths for outputting a current in response to the plurality of driving signals;
• and
• performing, by an inductive element, wireless communication corresponding to the data with an external device by receiving the current from the switches and generating an output signal based on the current,
• wherein the driver varies a level of the current corresponding to values of the data,
• wherein the driver generates the plurality of driving signals such that a first increase of an intensity of the current and a first decrease of the intensity of the current are alternately repeated in a first time interval to increase the intensity of the current from zero to an increased intensity that is less than or equal to a target value, and such that a second increase of the intensity of the current and a second decrease of the intensity of the current are alternately repeated in a second time interval to decrease the intensity of the current from the increased intensity to zero, and
• wherein the method further comprises:
• sensing, by a current sensor, the level of the current provided to the inductive element;
• and
• generating, by a driving controller, the control signal based on the sensed level.

A method of operating an electronic device, the method comprising:

• adjusting an intensity of a current such that the intensity of the current does not exceed a target value and providing the current to an inductive element of the electronic device;
• increasing the intensity of the current from zero to a first reference value that is equal to or less than the target value in a first time interval;
• decreasing the intensity of the current to a second reference value that is less than the first reference value in a second time interval in response to the intensity of the current becoming equal to or greater than the first reference value;
• increasing the intensity of the current in a third time interval in response to the intensity of the current becoming equal to or less than the second reference value in the second time interval;
• decreasing the intensity of the current to zero in a fourth time interval;
• and
• repeating alternately the second time interval and the third time interval between the first time interval and the fourth time interval.
