Advanced Methods of Analog Integrated Circuits Design

FEKT-MPC-NAIAcad. year: 2025/2026

The course deals with moderately advanced methods of analog integrated circuits with respect to a more detailed understanding of the parasitic effects in terms of accuracy and noise. Used technologies (bipolar, CMOS and BiCMOS).
The course content is:
- Design and simulation of a small analog system
- Methods for accurate design, calculation of matching (Matching Analysis)
- Noise analysis in theory and in practice

Practically-oriented exercises on real precision low-noise design of analog circuits.
Computer exercises with usage of the advanced software packages (Cadence).

Entry knowledge

The knowledge on the Bachelor´s degree level is requested. Students should be able to explain and work with the basic electrical engineering principles and laws, in particular the theory of circuits (circuit variables, Ohm's law, Kirchhoff's laws). The advantage is the prior completion of the course MPC-AIO (design and analysis of current mirrors, operational amplifiers, voltage bandgap references, etc.)

Rules for evaluation and completion of the course

Usually:
- 30 points for two written tests during semester
- 70 points for the final exam (written test + oral correction)

The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
Usually: Credit is conditional upon attendance in computer labs

Aims

The aim is to provide students with the orientation of advanced design methods of modern analog functional blocks for integrated circuits. Emphasis is put on the design of the precise low noise circuits. Students also learn to work with a professional design environment CADENCE at such a level that they will be able to design and draw a basic analog circuits and simple systems and simulate them using basic types of analysis.
After the course the student is able to:
- design a simple analog system (trained on analog circuitry for a switching power supply source controller)
- understand, explain and perform design and analysis of accurate analog integrated circuit (precise operational amplifier, precise voltage reference, precise current reference)
- design, analyze and optimize analog integrated circuit with regard to low noise requirements
(Emphasis will be placed on practical skills (engineering calculation, verification simulation).
