Oberseminar Schaltungstechnik (Advanced circuit design seminar)

If you are interested in this course for winter-semester 2021/2022, please contact us by email so that we add you to the list of participants for online lectures.

Contact: Dr. Bahman K. Boroujeni
Location: Online course because of current pandemic
Time:  Winter-semester 2021/2022; Thursdays, 4.DS=13:00--14:300
Leistungspunkte: 2 S 2 PL
Target groups: Diplom students in the 7th to 10th semester.

In this course you will learn about the technical aspects related to the design of analog circuits. In addition, you will learn how to present and publish your work. The course consists of:

• Around five weeks of lectures (one lecture per week) at the beginning of semester.
• A practical work in which you will design a circuit using LTspice which is a freeware circuit simulator widely-used in the industry and can be easily installed on your laptop or PC.
• You will make a presentation about your practical work.
• You will deliver a final written report about the topic of your practical circuit design work.
• There will be no written exam.

Lecture Contents

• Different types/frequency-responses/materials/applications of commercially existing capacitors, diodes, loudspeakers, etc.
• Examples of different commercially-available op-amp ICs; and designing circuits with them.
• Pulse circuits, switching power converters, and rectifier circuits. Examples of widely-used signal transistors and power transistors, their electrical characteristics and datasheets.
• Basics of op-amp design, gain, speed, swing, bandwidth, and power dissipation.
• Study and analysis of simple one-stage and two-stage op-amps.

Practical Works

You choose one topic from the options below. Please contact the supervisors if you want to suggest a new topics.

• Design of an audio filter and amplifier for compensating the imperfections in the frequency response of a piezoelectric loudspeaker.
• Design of a RFID energy harvesting circuit, including a coil and a rectifier circuit, for AC/DC energy conversion from a magnetic field at 13.56 MHz.
• Design of an energy-efficient switching DC/DC converter, e.g. 12 V to 5 V for automotive applicaions.
• Design of a folded-cascode operational transconductance amplifier (OTA) in CMOS, including bias network.
• Design of a two-stage OTA with pole-splitting compensation in CMOS.
