Abstract
A variable inductor is provided, which includes a first lead having both ends to receive a pair of difference signals, a second lead having both ends to receive a pair of the difference signals, and a switch selectively supplying a pair of the difference signals to the second lead by turning on/off according to a control signal. Accordingly, a variable inductor can be implemented that is compact and maximizes the variation rate of inductance.
