ABSTRACT:
A frequency-tunable arrangement comprises a resonance circuit having a capacitive part that is tunable throughout a capacitance range. A plurality of amplifiers is coupled to the resonance circuit so as to form an oscillation loop. At least one of the amplifiers is a switchable amplifier that is switchable between an active state and an idle state. The switchable amplifier causes a capacitance variation in parallel to the capacitive part of the resonance circuit when switched between the active and the idle state. The switchable amplifier is arranged so that the capacitance variation substantially corresponds to the capacitance range throughout which the capacitive part can be tuned.
