Langue:

English

Summary

Introduction to analog CMOS design for Remote Biosensors on Chip. Understanding and designing of active and remotely powered biosensing systems.

Content

Principles of biosensing: Target/Probe Interactions

Electrochemical biosensing: three-electrode electrochemical cell and its equivalent circuits

Basic CMOS configurations for electrochemical biosensing

Voltage-ramp generators on chip

Current readers: current-to-voltage and current-to-frequency conversion

Wireless transmission in lossy media: issues on temperature, specific absorption rate (SAR) and efficiency

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.

Power suppliers: non-rechargeable battery, rechargeable battery, super-capacitor, and storing capacitor

Different types of remote powering coupling between control units and remote biosensors

Passive (load modulation and backscattering) and active transmitters for RF communication

System Configuration for remote powering operation and data communication.
