Subject fundamentals
To understand and learn how to use electronic devices and systems typically adopted for the management of bio stimuli or of signals from sensors and transducers. Considering the involved frequencies the operational amplifier (OPAMP) will be a core element.
Expected learning outcomes
At the end of the course studnets will know how to:
1. analyze an electronic circuit in term of frequency response
2. compute the output of a circuit with a generic periodical input signal
3. use operational amplifiers to analyze and realize circuits and amplifiers
4. use instrumentation amplifier to handle bio stimuli and interface a sensor/transducer
5. choose the specific of the active and passive components to achieve the design constraints
Prerequisites / Assumed knowledge
Mathematical background from calculus and geometry courses. Knowledge of the physics ruling the electrical phenomena. Know how to solve an electrical circuit.
Contents
8 hours for the course introduction and to refresh the electrical basis.
20 hours for the labs group activities. Students will learn how to use the basic instrumentation (oscilloscope, multimeter, signal generator, power supply) and how to deploy bread board circuits.
10 hours to Fourier approach for circuit analysis. Bode diagram usage.
4 hours to introduce negative feedback concepts
10 hours to learn how to use ideal OPAMPS with example of the basic circuit
16 hours devoted to the most important OPAMP circuit: instrumentation amplifiers, complex pole filters, basic cell to realize second order filters
4 hours to present real OPAMPs and its main difference with the ideal case. The student will be taught how to read OPAMP data sheets
8 hours to solve old written tests and to simulate a written test.
Delivery modes
The course requires compulsory lab activities where the students will mount and test circuits, writing report on these activities. All blocks composing an ECG system will be realized: instrumentation amplifier based acquisition block, block for line 50 Hz rejection, and low pass filter block. All these blocks will be separately mounted and tested in a three hour lab session. Last lab will be devoted to the full ECG system assembly cascading the several blocks, and to test the complete systems. Any group have to test the system in its real operative condition, i.e., in presence of electrodes taking signal from a human body. Labs activities evaluated through the group reports and the individual behavior during the lab hours provide integration to the final score (max 2 points).
Texts, readings, handouts and other learning resources
Copy of the slides of the course already present at the beginning of the course and possibly integrate if necessary. A booklet with material covering the course program is also available.
Assessment and grading criteria
Passing the written test is mandatory. Generally, students achieving at least a 18/30 score have completed what needed, and the final score is the same of the written test integrated with the lab score. The teacher can however ask for a further oral test. Students with score between 15/30 and 18/30 must do an additional oral test. Students with score below 15/30 must repeat the exam. All students passing the written test (score at leats 18/30) can ask for an additional oral test.
