15-11-2022: Structured design of CMOS feedback amplifiers¶
Lecture: EE4109-1
Location: Pi
Time: 15:45 - 17:30
Goal of this lecture
At the end of this lecture the student:
Understands the Structured Electronics Design method
Understands the principle of amplification using passive devices and bias sources
Knows the performance aspects, the cost factors and the relevant environmental conditions for CMOS amplifiers
Knows which design techniques can be applied for improvement of the performance-cost ratio of amplifiers
Is able to set-up a performance specification for the active antenna (case study)
Is able to set-up test benches for the active antenna (case study)
Is able to define a project for the design of the active antenna
Prerequisite knowledge and skills¶
Chapter 1, Chapter 2, and Chapter 7 of Structured Electronics Design
The following topics from the Homologation course:
Modeling and characterization of the ideal behavior of amplifiers
Modeling and characterization of the non-ideal behavior of amplifiers
You are assumed to be familiar with SLiCAP
Chapters to study¶
Chapter 3 and Chapter 6 of Structured Electronics Design

Assessment
The final grade can be composed in 2 ways.
Students can decide to work in a design team during (max. six students) the course. Via several assignments in Brightspace during the lecturing period, a complete CMOS design is made by this team. The group defends this design during a review session. An appointment is made during or after the exam period for this review session.
Students can do a written exam.
The written exam is open for all students, also for students that are or were in a design team. Students not present during the review session will not receive the team grade.
