Short Description

In the history of computing platforms, from mainframes in the 1950s to workstations in the 1960s, personal computers in the 1980s, laptops in the 1990s and now the current smart phones, one of the most evident trends is the increasing convenience and frequency of access by humans who utilize the computing platform. Miniaturization of the computer is an important factor in this trend, lowering cost, reducing the required space and providing mobility. However, the need for physical access with an interfacing component like a screen, buttons or a touch surface limits its form factor and therefore inhibits further miniaturization. On the other hand, the next generation of computing platforms, which is the internet-of-things (IoT), improves proximity to the source of the information rather than to humans, allowing much more aggressive miniaturization. The key technology of miniaturization is the ultra-low power circuit design for shrinking volume of the battery. In this project, a student will learn basic techniques for circuits operating under highly restricted energy capacity by designing key building blocks of a miniaturized system such as analog front-ends, voltage/current/timing references, data transceivers, energy harvesters and power management.
