CMOS Readout Chips for Implantable Multimodal Smart Biosensors

Moustafa Nawito describes in detail the development process of a novel platform of Readout Integrated Circuits (ROICs), which enable the realization of miniaturized multi-parameter biomedical implants intended for long-term in-vivo monitoring. He presents new circuits and techniques for fully integrated sinusoidal generation, electrochemical impedance spectroscopy as well as on-chip measurement of pH levels, oxygen concentration and temperature. The author draws conclusions of the development process and delivers guidelines for further innovations.ContentThe SMARTImplant ProjectCyclic ADC with Offset SubtractionNew Sine-Wave Generation MethodNew Synchronous Impedance Spectroscopy MethodOn-Chip Temperature MeasurementUltra-Thin Chip ConsiderationsTarget GroupsLecturers, students and practitioners in the field of Electrical Engineering, Electronics, Medical Technology and BiotechnologyThe AuthorMoustafa Nawito is a mixed-signal electronic chip designer at the Institut für Mikroelektronik Stuttgart (IMS CHIPS) with focus on analog circuits.
