"Circuit Design for Biomedical Applications"
ABSTRACT
This presentation will consist of two parts. Firstly, it will discuss the use of ultra wide band (UWB) in biomedical implants. Wireless Body Area Network (WBAN) applications demand a power stringent operation, high data rate and low form factor. An Impulse Radio-Ultra Wide Band (IR-UWB) system transmits pulses with short duration to represent data. Because of the pulse-based nature of data transmission, simpler modulation schemes, such as pulse position modulation (PPM) and on-off keying (OOK) can be used in UWB based systems. This results in significant power savings over systems that use complex modulation schemes. Furthermore, because of the simplicity of UWB pulse generation, IR-UWB has a low hardware complexity when compared to other candidates such as OFDM based UWB, enabling low form factor and less power hungry hardware implementations. Secondly, this presentation will focus on developing a wireless powering scheme for implants that will also serve as a wireless data telemetry channel for communication purposes, while observing safe SAR (specific absorption rate) levels.
