Abstract

We are facing a new era of the Internet of things, similarly indicated as Industry 4.0, TSensors, Ubiquitous or The Fog. A miniaturized computer is the key to this innovation that senses, collects and processes information from objects. In this class, based on the recent publications, energy efficient analog IC techniques will be introduced which is the main challenge to reduce the battery size.

Objective

This class introduces key analog building blocks such as energy harvester, frequency generator, data converter, sensor interface, power converter based on the recent publications for IoT systems including wearable electronics, bio-implantable devices, and environmental sensors.

Content

Ultra-low power circuit design methodology and transistor characteristics; Circuit-level design techniques for amplifier, comparator, voltage reference, on-chip oscillator, switched capacitor; IP-level design techniques for energy harvester, data converter, energy harvester and power converters.

Examination

Type
graded semester performance
The final grade is composed of a design project (60%) and a final oral exam (40%).For the design project, students form groups of 4-5 and decide the project objective based on a recent conference or journal publication (we provide a set of publications for the students to make a choice).The design is performed during the exercise hours under the supervision of the lecturer and teaching assistants. In addition, we expect students to devote additional time to the design project (homework).The design project will be evaluated in three stages:1) In the mid-term project presentation, a student representing each group explains one's project in the aspects of operational principle, performance target and plan;2) in the final project presentation, the design outcome is explained including the accomplished novelty and performance;3) a written project report summarizes detailed explanation on the design.The overall evaluation is based on the mid-term project presentation (15%), the final project presentation (30%) and the project report (15%).The oral exam (30 min) will evaluate the qualitative understanding of the course material individually.
