The proposed algorithm uses a linear slope predictor to estimate the ECG samples, and uses a novel low complexity dynamic coding-packaging scheme to frame the resulting estimation error into fixed-length 16-bit format. The proposed technique achieves an average compression ratio of 2.25x on MIT/BIH ECG database. Implemented in 0.35μm process, the compressor uses 0.565K gates/channel occupying 0.4 mm2 for 4-channel, and consumes 535nW/channel at 2.4V for ECG sampled at 512 Hz. Small size and ultra-low power consumption makes the proposed technique suitable for wearable ECG sensor application. © 2013 IEEE. | Source Title: | Proceedings of the 2013 IEEE Asian Solid-State Circuits Conference, A-SSCC 2013 | URI: | http://scholarbank.nus.edu.sg/handle/10635/83467 | ISBN: | 9781479902781 | DOI: | 10.1109/ASSCC.2013.6691003 |
