Biomedical Instrumentation I

Catalog description

This course focuses on the fundamental devices, circuitry, and techniques needed to acquire and preprocess biomedical signals. Operating principles of basic semiconductor devices as well as their application are explained. The electrical characteristics of diodes, photodiodes, Zener diodes, LED, regulators, and BJT and MOSFET transistors are covered. Switched mode power supplies are introduced as an application. Filtering principles and filter types are demonstrated in detail. Additionally, operational amplifiers are studied and used in multiple amplifier and filter circuits to preprocess signals. Non-ideal op amp properties are treated in sufficient depth to permit design of high gain circuits capable of handling small amplitude and low frequency biomedical signals.
