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 130nm standard CMOS process achieving 9.12μW of power consumption and 91.2pJ per pulse at 100kbps data rate.

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 130nm standard CMOS process achieving 9.12μW of power consumption and 91.2pJ per pulse at 100kbps data rate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
