“…The measurement results prove that all the functions work well, and can achieve satisfactory performance. Compared to other existing ECG processors [3][4][5][6], our proposed ASIC can not only realize multiple necessary and critical functions for long-term ECG monitoring, but also achieve small-size and low-power. By embedding this on-chip ECG processor, the sensor node keeps small size while has powerful monitoring and analysis capability.…”

“…Many ECG processing platforms and devices are proposed [3][4][5][6]. Some of them can realize multiple functions but with comparatively large size and high power consumption [3], [4], and thus they are not quite suitable for miniature sensor node applications.…”

“…Some of them can achieve small size using the application specific integrated circuit (ASIC) design with limited functions. For example, [5] can realize QRS peak detection and [6] can suppress baseline drift (BD). However, limited functions may not satisfy comprehensive requirements of healthcare monitoring.…”

In this paper, a miniature low-power Electrocardiogram (ECG) signal processing application specific integrated circuit (ASIC) chip is proposed. This chip provides multiple critical functions for ECG analysis using a systematic wavelet transform algorithm and a novel SRAM-based ASIC architecture, while achieves low cost and high performance. Using 0.18 µm CMOS technology and 1 V power supply, this ASIC chip consumes only 29 µW and occupies an area of 3 mm(2). This on-chip ECG processor is highly suitable for reliable real-time cardiac status monitoring applications.

“…Other work [Lee et al 2007;Sakaue and Makikawa 2008;Teo et al 2009;Chen et al 2009] utilize either custom-made or other COTS processors, which are therefore difficult to compare to the previously mentioned platforms. In particular, it is worth mentioning the SNAP/LE [Ekanayake et al 2004], an asynchronous processor for lowpower WSNs that achieves less than 75pJ/instruction, with many instruction types using less than 25pJ/instruction, when running with a 0.6V supply voltage and a frequency of 23MHz.…”

In order to provide better services to elderly people, home healthcare monitoring systems have been increasingly deployed. Typically, these systems are based on wireless sensor nodes, and should utilize very low energy during their lifetimes, as they are powered by scavengers. In this article, we present an ultra-low power processing system for a wireless sensor node for very low duty cycle applications. In the CoolBio system-on-chip, we utilized several power reduction techniques at both the architecture level and the circuit level. These techniques include feature extraction, voltage and frequency scaling, clock and power gating and a redesign of key standard cells. In the design of the ultra-low power processing system, we paid special attention to the memory subsystem, as it is one of the most power-consuming modules in a design. We also designed a clock manager in order to reduce the power consumed by clocking, and a power manager that is able to power-off unutilized modules. The proposed wireless sensor node processing system consumes 36.4μW at 100MHz and 1.2V supply voltage, for a heartbeat-detection algorithm with a 0.01% duty cycle.

An ultra‐low‐power low‐voltage 401–406 MHz Medical Device Radiocommunications Service (MedRadio) receiver for continuous wireless communication in biomedical applications is demonstrated using 0.18‐μm CMOS technology. Although using a low‐IF architecture, careful consideration is done for individual block‐level circuit design to minimize the overall power consumption. The receiver chain consists of a complementary current‐reuse LNA, an in‐phase/quadrature folded mixer, an eighth‐order complex bandpass filter, a limiting amplifier chain with RSSI, and a frequency synthesizer with a quadrature VCO. The proposed receiver achieves a gain of over 80 dB, noise figure of 14 dB, image rejection of 32 dB, and phase noise of −106 dBc/Hz at 100 kHz offset while consuming less than 1.2 mW from a 1‐V supply voltage with 1.8 mm2 of core die area. © 2012 Wiley Periodicals, Inc.
