Abstract: A signal generation circuit includes a voltage controlled oscillator configured to generate a differential oscillator signal having an amplitude. A passive mixer has first differential inputs coupled to the voltage controlled oscillator to receive the oscillator signal. The passive mixer also includes second differential inputs. A filter circuit is coupled between the voltage controlled oscillator and the second differential inputs of the passive mixer. The filter circuit is configured to filter the differential oscillator signal as a function of the amplitude of the differential oscillator signal to thereby generate a filtered differential oscillator signal and to provide the filtered differential oscillator signal to the second differential inputs of the passive mixer.
