Course DescriptionOverviews discrete semiconductor devices - diodes, BJTs, and FETs - and operational amplifiers. DC models as well as frequency response, bandwidth/rise time relationships, and performance criteria are emphasized. Labs emphasize circuit construction and include simulation of amplifier circuits. Prerequisite: MT 112. Audit available.
Addendum to Course DescriptionThe laboratory portion of this course provides students with the opportunity to develop skills in the operation of electronics test instruments (signal generators, digital multimeters and oscilloscopes). Students will work in teams of two or more to perform and complete laboratory exercises. Students must be able to communicate, both in oral and written form, using the English language.
Intended Outcomes for the course
- Construct, analyze and troubleshoot circuits which incorporate semiconductors devices and linear ICs e.g. operational amplifiers
- Operate electronic test equipment: multimeters, power supplies, signal generators and oscilloscopes.
- Use electronic circuit simulations e.g. PSpice
- Read and interpret technical materials e.g. schematic diagrams and device data sheets.
- Communicate technical information in written and oral form
- Practice safe operating procedures.
The course will include a variety of learning activities. The lecture portion of the course will include instructor delivered lectures and demonstrations stressing key topics in the course. In preparation for the lecture portion of the course, students will be expected to complete all reading and homework assignments.
The laboratory portion of the course is intended to enhance skill in the operation of basic electronic test instruments, skills in circuit analysis and troubleshooting, skill in teamwork, and skills in oral and written communication.
Outcome Assessment StrategiesAssessment of student performance in this course will be conducted in both the lecture and the laboratory portion of the course and will be in the form of written and practice-based questions.
