Abstract
The invention relates to an oscillator circuit comprising: a VCO core having an output terminal for providing an oscillatory output signal thereat and having a supply terminal for receiving a supply voltage from a voltage supply, a subsequent circuit coupled to the VCO core's output terminal and having a supply terminal for receiving a supply voltage from the voltage supply. According to the invention, a decoupling member is arranged between the VCO core's supply terminal and the subsequent circuit's supply terminal for preventing high-frequency signals generated by the subsequent circuit at its supply terminal from entering the VCO core. The decoupling member may comprise a transmission line the length of which is one quarter wavelength associated with a second-harmonic oscillation.
