goals

Smartphones for various type of cellular networks and standards includes complex systems inside. Various functions are realized by highly integrated on-chip systems (System on a Chip, SoC). These SoC include a large amount of circuits on the same chip. The students will learn the most important integrated circuits in the analog part of the mobile phone and will learn the up-to-date solutions in advanced nano-scaled CMOS-technologies. Thereby you will gain a deep insight into fundamentals of analog RF circuits used in a mobile phone. You will understand how the basic transceiver architectures work. Furthermore, you will see how the principles of high-frequency engineering and communication theory are applied in modern cellular systems integrated monolithically on a silicon chip.

content

After an overview of the most important cellular standards and the modulation schemes, first the basic transceiver architectures will be discussed. The considerations on the integrated circuits which are used in the transmit and receive paths are discussed. These include low noise amplifiers (LNA), mixer, voltage-controlled oscillators (VCOs), frequency dividers, Power Amplifiers (PA) and ADCs. For each circuit block we will present the theoretical background and then practical examples of transistor level, including circuit simulations, schematics and measurement results.
