Abstract

Rapid development of sensor technologies, CMOS fabrication processes and wireless sensor network technologies have unlocked new and innovative applications of health monitoring systems. For long-term reliable detection of various biological signals in point-of-care health monitoring systems it is essential to provide adequate power savings for the associated electronic circuits. A solution for designing low-power and high-performance integrated circuits for readout electronics involves implementation of machine learning/deep learning algorithms into CMOS integrated circuits to process any type of physiological signals, including respiratory, ECG or EEG signals. Various machine learning models, such as deep learning architectures, have been employed to design intelligent healthcare systems. However, deploying these sophisticated and intelligent devices in real-time embedded systems with limited hardware resources and power budget is complex due to the requirement of high computational power in achieving a high accuracy rate. As a result, this creates a significant gap between the advancement of computing technology and the associated device technologies for healthcare applications. Power-efficient machine learning-based digital hardware design techniques have been introduced in this work for the realization of a compact design solution while maintaining optimal prediction accuracy. This has a potential to become a versatile signal processing hardware platform for biomedical instrumentation. Integrating machine learning functions and algorithms into a single CMOS integrated circuit and implementing it in a deep submicron CMOS process targeting very low power consumption will be a potential new approach to the development of future wearable medical devices and technologies.
