Title: Baseband Integrated Circuits Design in the Era of 5G and IoTs: New Paradigms?

Abstract: Recent developments in mobile computing and wireless internet have led to an increasing demand for portable computers and smart phones equipped with wireless local area network (WLAN) operating with multi-standard capabilities. Mobile phone vendors shipped a total of around 334 million units in the first quarter of 2015, and sales continuous increasing at a rate of approximately 20% per year. This tendency will continue in the coming years. More standards and applications will be incorporated in the near future because minimum feature size transistors in VLSI technology allow more devices on a single chip with massive digital signal processing and memory capabilities. The era of Internet of Things (IoT) elevate the connectivity of devices to a levels never seen before. The emerging applications will allow the use of bandwidths over 160MHz for in-house short range communications. The market of the Front-end modules expects to grow from $10.1B in 2016 up to $22.8B in 2022. The growing demand for high speed and high precision analog integrated circuits dictates stringent design specifications for the required building blocks; among others, the RF front-end (LNA, Power Amplifier, filters and tuning of Antennas) are recognized as the big challenges for the emerging standards. In baseband, the high performance ADCs is an unavoidable block and always remain as a challenge when migrating to more advanced nodes and more demanding specifications; e.g. higher bandwidth and higher resolution. The ultimate limit for the design of systems on chip is the restricted power consumption, making the power management system very critical especially for battery operated devices. In this seminar, the design aspects of circuits and systems for advanced ADCs as well as power management circuits are re-visited. The technological challenges and demanding specifications will be discussed, and relevant solutions will be analyzed. The most relevant cases addressed in this presentation will include low-dropout regulators, sigma-delta modulators and pipeline ADCs. We will show that the solutions for the new technological challenges are still based on the fundamental principles of IC design. We will show that the fundamentals on control theory are the main tool needed, as well as a thoroughly characterization of your technology. The trend towards faster and smaller transistors offer opportunities to address the challenges posed by the 5G and IoT applications.
