Abstract: An automotive radar apparatus includes a bit stream modulation circuit configured to generate a bit stream signal at an output thereof and a driver circuit having an input coupled to the output of said bit stream modulation circuit and configured to generate a corresponding driver bit stream signal having a reduced output swing at the driver circuit output. Also included is a filter circuit having an input coupled to the output of said driver circuit and configured to generate a filtered bit stream signal at the filter circuit output. Additionally included is a VCO having an input coupled to the output of said filter circuit and configured to generate an RF output signal at the VCO output. A corresponding method is also provided.
