Ultra-Low Power Transceiver Design

Abstract

Many emerging medical application systems require the wireless communication functions. Nowadays, wireless medical application for sensing purposes such as the long term electrophysiology signal (ECG, EEG, etc.) monitoring (Yoo et al. IEEE International Solid-State Circuits Conference, ISSCC, 2012, pp. 292–294), the digestive tract imaging with the wireless endoscope capsule (Jiang et al. IEEE Asian Solid State Circuits Conference, A-SSCC 2010, pp. 1–4), the fetal heart sounds tele-examination (Yang et al. IEEE Biomedical Circuits and Systems Conference, BioCAS, 2012, pp. 356–359) and the real-time pressure sensing in artificial joint replacement surgeries (Chan et al. Analog Integrated Circuits and Signal Processing 72(2):293–302) have gained many remarkable achievements. Also, the wireless medical applications for intervention purposes such as neural stimulation for cochlear implants (Mai et al. Annual International Conference of the IEEE Engineering in Medicine and Biology Society, EMBC, 2012, pp. 6595–6599.) and insulin delivery with closed-loop control (Jacobs et al. Conference of the IEEE Engineering in Medicine and Biology Society, EMBC, 2011, pp. 397–400) have preliminarily demonstrated the clinical practice value.
