Advances in CMOS SoC radar sensor for contactless cardiac monitoring

The advances in the implementation of the wearable system-on-chip pulse radar sensor for contact-less cardiac monitoring, designed and fabricated in 90 nm CMOS technology, are presented. The LNA, pulse generator and delay generator have been measured and their performances have demonstrated a good agreement with the simulation results. A review of the feasibility study based on building-block measurement results and system simulations confirm at this stage the results of the preliminary feasibility study.
