Proc. of the 5th Joint Symposium on Opto- and Micro-Electronic Devices and Circuits
This paper presents circuits for 77 GHz automotive
radar applications in SiGe bipolar technology. Key building
blocks are presented, including voltage-controlled oscillators, frequency
dividers, downconversion mixers and low noise amplifiers.
As a next step, the authors present a fully integrated 4-channel
FMCW-Radar based transceiver in a SiGe production technology.
The second part of the paper outlines future trends in the area
of SiGe automotive radar. The latest european research projects
in the field are introduced, together with their goals and the
impact on future SiGe radar systems.
