High Speed Mixed-Signal IC

Through five decades of continued transistor scaling, the size of unit computing has gone to virtually zero. In the foreseeable future, Computing will be all around us, in mostly invisible forms, leading to 50+ billions of connected devices to the Internet (Internet of Things or IoT). Increasingly, connectivity has become an indispensable part of modern computing devices. By some estimates, IoT devices will generate 3+ exabytes (one billion gigabytes) of data per day by 2018. The various communication fabrics that will handle this enormous amount of data needs to be extremely energy-efficient. The advance and prosperity of CMOS technology has enabled design of these communication fabrics using mixed-signal and digital-heavy techniques, which allows for lower power, reconfigurability and faster time-to-market. This course will build basic understanding of such mixed-signal circuits and systems and highlight their use in communication systems (wireline IO, wireless), which are becoming increasingly important in the data-driven world. A design project will be a key component of the course. The students will conduct a group design project that will help them obtain practical design knowledge and skills and exposure to Process Design Kit (PDK) and EDA tools like Cadence Schematic Editor, Layout Editor, and Simulator (Hspice or SpectreRF).
