Abstract:
A variable inductor structure for varying an inductance responsive to a digital tuning signal, comprising: a first inductor; a second, adjustable, inductor; and a digital control mechanism configured to receive the digital tuning signal and to adjust the effective inductance of the second inductor in response to the digital tuning signal; wherein the second inductor is positioned sufficiently close to the first inductor so as to be capable of altering by mutual inductance the effective inductance of the first inductor in dependence on the digital tuning signal.
