Abstract
Disclosed is a spiral inductor formed on a semiconductor substrate. The spiral inductor comprises: a metal line forming a spiral pattern on a substrate using conductors having different widths and having open or short-type stubs at one side of each of the conductors; and switching means connection-controlled in accordance with a selection signal for adjusting an inductance and selectively connecting the conductors of the different widths of the metal line. According to the invention, the open or short-type stubs may be formed at one sides of each of the conductors, thereby inducing a parasitic capacitance or parasitic inductance. Based on the inducement of the parasitic capacitance or inductance and selectively connection of the conductors to one another through switching means, it is possible to accurately control a whole inductance value of the spiral inductor, depending on use purposes.
