Modeling of Electronic Components for Integrated Circuits

Course Description

The aim of this course is to provide specialist knowledge and skills in the field of modeling of micro- and nanoelectronic components for integrated circuits, which allows reliable simulations in order to accelerate and decrease the cost of integrated circuit design. The course covers: modeling principles and DC, AC, transient, high-frequency and noise simulation; drift-diffusion model and its application in the analysis of advanced transistors such as FinFETs; empirical and physical models for unipolar and bipolar transistors implemented in different technologies; implementation of efficient models using C and Verilog-A. The course will provide a thorough understanding of the design process, from measurement, over model implementation and calibration, to designing a demonstration circuit on a computer.

Learning Outcomes

  1. Understand the connection between measurements, implementation and calibration of the model, and circuit design.
  2. Choose an appropriate modeling approach depending on the application and software environment.
  3. Apply programming languages C and Verilog-A for model implementation.
  4. Explain the modeling methods for DC, AC, transient, high-frequency and noise simulations.
  5. Implement a (process) design kit in an electronic circuit simulation software package.
  6. Implement simple simulation software in C using advanced numerical libraries.
