Abstract

A 1.6-to-3.8GHz FMCW radar SoC for real-time non-line-of-sight life detection is implemented in 40nm CMOS. An 81.5% BW ring-VCO PLL with DTC achieves 29.6kHz frequency error and 0.78-to-400MHz/μs chirp slopes. The TX integrates a 13.43dBm PA, while the RXRF features 8.1dB NF, baseband chain with 100dB-rejection SC-HPF at 1kHz and CT Δ-Σ ADC. A RISC-V core with FPU/VPU enables DSP, detecting people behind 6 walls and vital signs behind 2, occupying 7.65mm² and consuming 0.395W.
