Analog circuits for biochip

EE-518 / 3 crédits

Enseignant(s): Carrara Sandro, Schmid Alexandre, Skrivervik Anja

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
