VARIABLE INDUCTOR AND SEMICONDUCTOR DEVICE USING SAME
摘要
<p>Provided is a variable inductor, the inductance value of which can be changed without increasing an occupied area. The variable inductor (1) according to the present invention comprises: a spiral inductor (2); a loop conductor (5); and a switch (7) for opening or short-circuiting an end of the loop conductor (5). The loop conductor (5) is formed in a direction perpendicular to the spiral inductor (2) and is used for adjusting the inductance value of the spiral inductor (2) by opening or short-circuiting the end of the loop conductor (5) by the switch (7).</p>
