Provided is a control device of a LC circuit using a spiral inductor, comprising: a spiral inductor in which a first metal line connected to a first terminal and a second metal line connected to a second terminal cross at least one time to be connected in a spiral shape, and that includes at least one crossing part; at least one transistor in which a drain terminal and a source terminal are respectively connected to a first metal line portion and a second metal line portion that correspond to the crossing part; a variable capacitor that is connected to a first terminal and a second terminal of the spiral inductor in parallel; and a controller that respectively sends control signals to the transistor and the variable capacitor to control a resonant frequency or an output. |
