Various embodiments relate to an electronic device for realizing and controlling a section search-based discrete variable and an operating method thereof.

In general, passive elements are used in electrical and electronic circuits, and perform consumption, accumulation, and emission of supply power. For example, the passive element includes at least one of a resistor, a capacitor, and an inductor. In addition, the passive element may be used to implement voltage and current intensity adjustment, signal filtering, resonance matching, and the like on an electric/electronic circuit. The implementation (or type) of the passive element determines the extent to which the supply power is consumed, accumulated, and dissipated in the passive element. Accordingly, the passive element has a fixed electrical characteristic, that is, at least one of resistance, capacitance, or inductance. In general, since an electronic device includes a passive element having an electrical characteristic of a fixed value according to a specific driving environment, the performance of the electronic device decreases in response to a change in the driving environment, for example, a change in a load, a change in an input voltage, and the like. can be
