摘要： The invention relates to a voltage controlled oscillator for generating a variable frequency. The oscillator comprises an oscillator core and a transconductive portion for compensating current losses in the oscillator core. The oscillator core comprises an inductive portion with at least one inductive element and a capacitive portion whose capacitance can be continuously varied by means of a control voltage for varying said frequency. The capacitive portion comprises multiple variable capacitive elements whose capacitance is continuously variable by means of said control voltage, each variable capacitive element being switchable for being added to or removed from the capacitive portion.
