The present disclosure relates to tuning oscillatory systems. The teachings thereof may be embodied in a device having an adjustable capacitance value for tuning a first oscillatory system, connectable to a second oscillatory system having an unknown and weak coupling factor. The device may include: a first capacitor having a capacitance dependent upon a voltage; and a DC voltage source having a variable voltage applied to associated terminals; a series-connected arrangement of the DC voltage source and a decoupling element connected in parallel with terminals of the capacitor, to apply a variable bias voltage to the first capacitor. The voltage applied to the terminals of the DC voltage source may depend at least in part on a working frequency of the first oscillatory system.
