Abstract :
This paper presents the modeling and optimization of a frequency synthesizer dedicated to FMCW radar applications. This frequency synthesizer based on a type-I PLL presents the advantages of a simplified architecture with less potential electronic drawbacks. A methodology to optimize the filter loop is proposed in order to obtain the required smoothed frequency characteristic and correct the VCO distortion.
