Abstract

An electronic device includes a transmitter circuit, an inductive element, and a boost converter. The transmitter circuit outputs a current, which has a varying level, based on a supply voltage. The inductive element generates an output signal based on the current, such that wireless communication with an external device is performed. The boost converter boosts a system voltage to output the supply voltage. A voltage level of the supply voltage provided from the boost converter to the transmitter circuit based on the boosted system voltage is maintained to be equal to or higher than a reference level which is higher than a voltage level of the system voltage, regardless of a decrease in the voltage level of the system voltage.
