Analog Integrated Circuits
Entwurf Analoger Integrierter Schaltungen
The continuous progress in the field of integrated circuits and systems makes it possible to integrate more complex functions with ever-increasing operating speeds in a system-on-chip approach. The basic module "Analog Integrated Circuits" is teaching the analog concepts and basic circuit techniques that are used in integrated analog circuits. As part of a practically-oriented training part, the skills to master independent basic circuit design, simulate and develop the layout are taught.
In this course the following topics will be covered:
1. Design and layout of integrated passives
2. MOSFET small and large signal behavior, stability and Bodeplot
3. MOSFET basic circuits such as current mirrors, common-source amplifier circuits, common-gate amplifier circuits, noise
4. Operational amplifiers, differential stage, frequency compensation
Digital Integrated Circuits
"Integrated Circuits" - Fundamentals of silicon integrated circuit technology: transistor models from a circuit point of view; basic analog and digital circuits; static and dynamic behavior; bistable circuits; MOS logic families; practical use of Spice simulations and layout editor.
Students will be able to program programmable digital systems in assembler language. They will be able to describe how a program written in a high-level programming language is translated into machine language and executed by a digital system. Furthermore, they will be able to derive the logic operations involved in processing machine instructions in a digital system at the register transfer level and develop extensions. In addition, students will be able to interpret the number representations used in digital systems and solve arithmetic operations using underlying microalgorithms. They will be able to represent the basic structure of digital systems, including input/output organization, memory hierarchy, and elementary structural principles of computers.

Advanced Analog Integrated Circuits and Systems
The continuous progress in the field of integrated nanoelectronic circuits and systems makes it possible to integrate more complex functions with ever-increasing operating speeds in a system-on-chip approach. The module "Advanced Analog Integrated Circuits and Systems" addresses these technological development and focuses on the analog basic circuits and concepts necessary for application areas such as wireless infrastructure applications (eg LTE), transceiver systems for electro-optical applications (eg Silicon Photonics) power dissipation low sensor systems for biomedical applications (eg nerve stimulation) or topics of automotive electronics or Internet-of-Things (IoT) are fundamental.
This course will cover the following topics:
1. High speed transceiver architecture, mode of operation and building blocks
2. Switched capacitor circuits, SC integrator, SC amplifier, SC filter, sampling operation, discrete time operation

MMIC4U Microwave Chip Project
The students are familiar with the essential concepts and, in particular, applied tools for integrated RF circuit design and analysis. Within the scope of a practically oriented training part, they have the ability to independently design, simulate and design (layout) the microchip for production as well as test them experimentally in the laboratory.
Due to increasing chip-integration, especially in communication technology, a fundamental and design-oriented understanding of integrated monolithic high-frequency and ultra-high-frequency circuit systems is becoming increasingly important. Thus, modern receiver and transmitter modules are more frequently used in the microwave and millimeter wave range. For this purpose, classical transistor (MOS, bipolar) circuit design and high-frequency RF design are combined together and applied with industry-standard design software and technologies (CMOS, SiGe). In addition to the analysis, the course teaches and strengthens skills in design synthesis (i.e. the circuit implementation) of high-frequency amplifiers for radio front-ends, including receivers (low-noise amplifiers), and transmitters (power amplifiers). In this context, synthesis also means, in particular, the design flow for the optimization and validation of the mixed-signal RF circuit design, including the layout and post-layout verification methods, to finally give the designed circuits to a semiconductor Fab for production. This will indeed happen thanks to the support of IHP Leibniz Institute, Frankfurt (Oder).
MMIC4U (Microwave Monolithic Integrated Circuit for YOU): Together with the IHP Leibniz Institute, the three events are organized in such a way that the chip designs are produced between the two semesters (February to May). That is, each student group has their own chip design fabricated at the beginning of the second semester. The first semester focuses on applied theory including design calculations, circuit topologies, and design tool tutorials (MMIC4U Chip Class), as well as the actual design project with guidance in our student design lab (MMIC4U Chip Project) – the target is the design and implementation of a 5 GHz WiFi transceiver circuit completed for fabrication. The focus of the second semester is to conduct experimental lab evaluations under guidance. In a natural lab environment, basic analysis and measurement methods can be learned and practiced on their own chip. Thus, the students are getting the experience of a complete design, production and characterization cycle.
