Actual circuit cheap radar front-end will allow implementation in less expensive economy cars, enough to contribute to traffic safety. Cost reduction requires high-level integration of microwave front-end circuits, especially analog and digital circuit blocks co-located on a single chip. This book presents design, implementation, and characterization of a microwave receiver circuit in CMOS and SiGe bipolar technology. 0.13 Application of digital technology? M standard CMOS sensors for the realization of a narrow 24-GHz radar front-end investigation.
