M-Sequence Radar for High Resolution Ranging with Mixed-Signal Radar Receiver Baseband Using 130nm SiGe BiCMOS Technology

An m-sequence radar with a high chip rate of 20 Gcps is presented that makes use of the large bandwidth available in the V-band (40–75 GHz) or at 240 GHz to reduce the detection resolution to 7.5 mm. Measurement results of a mixed-signal radar receiver baseband (BB) integrated circuit designed using 130 nm SiGe BiCMOS technology are presented along with a novel radar ranging concept for the mixed-signal radar BB.
