<p>The invention relates to an oscillator circuit (10) comprising: a VCO core (8) having an output terminal (56) for providing an oscillatory output signal thereat and having a supply terminal (60) for receiving a supply voltage from a voltage supply (28), a subsequent circuit (6) coupled to the VCO core's output terminal (56) and having a supply terminal (72) for receiving a supply voltage from the voltage supply (28). According to the invention, a decoupling member (82, 83) is arranged between the VCO core's supply terminal (60) and the subsequent circuit's supply terminal (72) for preventing high-frequency signals generated by the subsequent circuit at its supply terminal (72) from entering the VCO core. The decoupling member (82, 83) may comprise a transmission line the length of which is one quarter wavelength associated with a second-harmonic oscillation.</p> |
