Low‐power low‐data‐rate IR‐UWB transmitter for paediatric apnoea monitoring system

Abstract

Wireless telemetry has recently become a very important feature for healthcare monitoring and wearable systems. Several factors such as reliability, power budget, and cost impose design constraints for data transmission. Literature reported transmitters characterised by lower energy efficiency for low data rate operations and are not quite suitable for low-power biomedical applications. To overcome these constraints, this paper presents an impulse radio ultra-wideband (IR-UWB) transmitter that implements a heavy duty-cycling approach to achieve low power consumption. The transmitter is designed to be used for a non-invasive wireless respiration monitoring and apnoea detection system for premature infants. The transmitter is designed and fabricated in 130 nm standard CMOS process achieving 9.12 µW of power consumption and 91.2 pJ per pulse at 100 kbps data rate.

An Overview of Signal Processing Techniques for Remote Health Monitoring Using Impulse Radio UWB Transceiver

“…The authors have compared the accuracy and reliability of radar measurements with those of conventional impedance pneumography measurements [104]. One such research work carried out by Mahbub et al [105] has designed an IR-UWB transceiver to be used for the remote monitoring of respiration signals and apnea detection in a non-invasive way for premature infants. The transmitter is designed and fabricated in a 130 nm standard CMOS process that consumes extremely low power of 9.12 µW.…”

Design of Reconfigurable Bandwidth Filtering Antenna and Its Applications in IR/UWB System

“…IR-UWB is widely studied with low power consumption, high bandwidth, easy compatibility, and low cost. A lot of research has also been carried out for the core IR-UWB antennas [1][2][3]. Sun-Woong analyzed a traditional antenna with high gain features for 2D indoor wireless positioning [4].…”
