A 345 µW Multi-Sensor Biomedical SoC With Bio-Impedance, 3-Channel ECG, Motion Artifact Reduction, and Integrated DSP
Nick Van Helleputte,Mario Konijnenburg,Julia Pettine,Dong-Woo Jee,Hyejung Kim,Alonso Morgado,Roland van Wegberg,Tom Torfs,Rachit Mohan,Arjan Breeschoten,Harmke de Groot,Chris Van Hoof,Refet Firat Yazicioglu +12 more
TL;DR: This paper presents a MUlti-SEnsor biomedical IC (MUSEIC), which features a high-performance, low-power analog front-end (AFE) and fully integrated DSP achieving 10 × or more energy savings in vector multiply-accumulate executions.
Proceedings ArticleDOI
A 2.4GHz/915MHz 51µW wake-up receiver with offset and noise suppression
TL;DR: An envelope detector is a popular choice in WuRx because of its low power consumption, but the detector is always the bottleneck of the receiver sensitivity since it attenuates low level input signal and adds excessive noise.
Proceedings ArticleDOI
9.8 An 860μW 2.1-to-2.7GHz all-digital PLL-based frequency modulator with a DTC-assisted snapshot TDC for WPAN (Bluetooth Smart and ZigBee) applications
Vamshi Krishna Chillara,Yao-Hong Liu,Bindi Wang,Ao Ba,Maja Vidojkovic,Kathleen Philips,Harmke de Groot,Robert Bogdan Staszewski +7 more
TL;DR: This work presents a 2.1-to-2.7GHz 860μW fractional-N ADPLL in 40nm CMOS for WPAN applications, which breaks the 1mW barrier and consumes at least 5× lower power compared to state-of-the-artADPLLs.
Journal ArticleDOI
Low-power wireless sensor nodes for ubiquitous long-term biomedical signal monitoring
TL;DR: This article introduces low-power wireless sensor nodes for biomedical applications that are capable of operating autonomously or on very small batteries and provides a system-level model for WSNs that helps in guiding the power optimization process with respect to various trade-offs.
Proceedings ArticleDOI
A 30fJ/conversion-step 8b 0-to-10MS/s asynchronous SAR ADC in 90nm CMOS
TL;DR: This work describes the implementation of an 8bit asynchronous SAR ADC that achieves a 30fJ/Conversion-step power-efficiency for sampling rates between 10kS/s and 10MS/s.
