A voltage controlled oscillator (200) has a tank circuit (210) with a first varactor diode (201), a transistor (225), a serial arrangement of a capacitor (202) and a second varactor diode (203) that is via a feedback node (215) coupled to the transistor; the capacity of both first and second varactor diodes is controlled by a common tuning voltage (VTUNE)
