Practicum/Tutorial
Bi-weekly 3h, supervised laboratory/tutorial sessions where the students will
verify theory and apply the theory to practical real-time system problems. Students are
working in groups of two in the laboratory and tutorial. Team work is expected. All team
members will have a same mark. There will be 6 labs + 1 tutorial in this class. The
students must perform all the labs and submit the report for each lab. Topics include:
1. Non-ideal operational amplifier and op-amp circuits: In this lab, the students
evaluate characteristics of the non-ideal operational amplifiers. Students will built
two most popular configurations op-amp circuits (inverting and non-inverting
amplifiers), predict the results, and observe the gain and frequency response.
2. Diode characteristics and diode circuits: At the end of this lab, the students
should be able to compare the experimental data to the theoretical curve of the
diodes. The students use the curve tracer to plot the I-V characteristics of the
diodes. The students also construct rectifier and filtering circuits using diodes and
capacitors.
3. BJT I-V characteristics: Students identify the current-control terminal of a threeterminal active device. The students will use the scanned-load-line methods to
obtain the I-V characteristic of the BJTs and compare with the characteristics
provided by the manufacturer.
4. BJT amplifier: In this lab, students design and implement single-stage BJT
amplifiers and observe amplitude and frequency response.
5. MOSFET I-V characteristics: In this lab, the students discover two voltagecontrol terminals of the four-terminal MOSFET. The students will construct the
circuit to explore the change in transconductance due to the change in substrate
voltage. The students will collect and analyze data to find the transductance
parameter of a particular MOSFET. The students will acquire the MOSFET I-V
by setting up a simple circuit connecting to the Analog Discovery Kit.
6. FET amplifier: In this lab, students design and implement single-stage FET
amplifiers and explore the frequency response of the real amplifiers.
HEALTH AND SAFETY
Any laboratory environment may contain conditions that are potentially hazardous
to a person’s health if not handled appropriately. The electrical engineering
laboratories obviously have electrical potentials that may be lethal and must be
treated with respect. In addition, there are also mechanical hazards, particularly
when dealing with rotating machines, and chemical hazards because of the
materials used in various components. Our LEARNING OUTCOME is to educate
all laboratory users to be able to handle laboratory materials and situations safely
and thereby ensure a safe and healthy experience for all. Watch for posted
information in and around the laboratories, and on the class web site.
