Key result
A 130nm CMOS wireless multiple sensors System-on-Chip for healthcare monitoring was developed, featuring a 6.25mm2 die area and consuming only 93μW with a 1% duty-cycling protocol.
The development of a low-power wireless SoC for continuous monitoring of ECG, bio-impedance, and temperature demonstrates feasibility for wearable healthcare devices.
May enable continuous multi-parameter wearables; leaves open clinical validation before routine use.
This paper presents an integrated wireless multiple sensors System-on-Chip (SoC) for healthcare including 3-lead ECG, bio-impedance (Bio-Z), and body temperature. To allow continuous and real-time monitoring, the SoC has included a multi-channel reconfigurable QPSK/BfSK transmitter (TX) to accommodate different power-constraint conditions. Fabricated in 130nm CMOS technology with a total die area of 6.25mm 2 , our SoC only consumes 93μW with 1% duty-cycling protocol in 0.9V supply.
