A controllable LC oscillator circuit has a resonant circuit including an inductance and a capacitance disposed in parallel. The oscillator is driven by an amplifier and the inductance is produced using coupled coils. The effective inductance of the coupled coils can be set by changing a gain of the amplifier, and a magnitude of the coupling factor of the coupled coils defines a magnitude of an adjustable frequency band of the oscillator. |
