A fully integrated 75–83 GHz FMCW synthesizer for automotive radar applications with −97 dBc/Hz phase noise at 1 MHz offset and 100 GHz/mSec maximal chirp rate
We present a SiGe BiCMOS fully integrated 75–83 GHz FMCW synthesizer for automotive radar applications. Performance enhancements were achieved by utilizing the bulk-drain parasitic variable capacitance of P-channel transistors, embedded in a gm-boosted Colpitts VCO, for frequency control. This mechanism was incorporated in a dual path PLL, providing low loop bandwidth variation over the whole output frequency range, −97 dBc/Hz phase noise at 1 MHz offset and maximum chirp rate of 100 GHz/mSec.
