Radar transmitter implemented in 28nm CMOS
Claiming a world first, Belgian research institute imec has demonstrated a continuous wave radar transmitter implemented in 28nm CMOS that operates in the 79GHz band.
With a supply voltage of 0.9V, the transmitter front end consumes just 121mW and is fully compliant with the spectral mask imposed by ETSI.
Developed in collaboration with Belgian university Vrije Universiteit Brussel, imec says it will pave the way towards full radar-on-chip solutions for automotive and smart environment applications.
After developing receiver functionality, the next step for the researchers is to build a complete multi-antenna lab prototype by the end of 2015.
After that, A/D converters and digital logic will be added to enable a full SoC.
