EE-518 / 3 crédits
Enseignant(s): Schmid Alexandre, Skrivervik Favre Anja, Carrara Sandro
Langue: Anglais
Summary
Introduction to analog CMOS design for Remote Biosensors on Chip. Understanding and designing of active and remotely powered biosensing systems. Basic understanding of eh wireless transmission of teh obtained signals.
Content
Principles of biosensing: Target/Probe Interactions
Electrochemical biosensing: three-electrode electrochemical cell and its equivalent circuits
Basic CMOS configurations for electrochemical biosensing
Current readers: current-to-voltage and current-to-frequency conversion
Wireless transmission in lossy media: issues on temperature, specific absorption rate (SAR) and efficiency. Antennas for such devices
Regulation aspects of wireless transmission close or in living matter: maximum value of the SAR and the temperature with respect to the frequency of operation and the body tissue.
Architecture of a biomedical implant and major blocks
Fundamentals of biomedical data transmission, data transmitters (active transmitters for RF communication)
Passive data transmitters (backscattering, load modulation), data receivers
Remote powering of implants (types and inductive remote powering, battery charging)
Data conditioning (spike detection, compression)
Keywords
OpAmp, CMOS, biosensors, RF communication, Remote Powering, wireless transmission
