For decades, the microelectronic research and development produced cheaper, faster, and more reliable electronics. Today, electronic chips form the backbone of our internet connectivity, through our computers, cell phones, sensors on human body, sensors at homes, home appliances, cars and roads. Today, microchips connect us to everyone and everything around us. However, the desire for more is far from over. We are interested in unprecedented speeds of communication, in transmitting and receiving information at rates beyond 100 billion bits per second (100Gb/s), and at a fraction of energy and cost we spend today for every bit. The aim of this research is to fulfill this desire and to enable reliable data communication at beyond 100Gb/s.This research will explore possibilities in four areas related to communication between microchips: 1. We explore the limits of information communication when two microchips are connected with copper wires. We would like to identify the impediments to speed of communication in order to realize what speed is theoretically possible and what is not. Once we find the boundaries of the two, we will attempt to achieve what is theoretically possible. 2. We explore methods of signaling where more information is packed per each use of the channel, cramming more than one bit per symbol, hence increasing the overall speed of communication. 3. We explore methods to revive the signal, to restore the data, before it vanishes in noise, and by doing so, will allow the data to go to a longer distance. 4. We explore methods of eliminating wires when two microchips are sitting side by side, using instead electromagnetic coupling as a means of reliable data communication. In this method, we need to design electronics to reliably launch our transmit signal onto a coil and to reliably receive and detect this signal at the other end while we make the coils as small as possible so as to incorporate more of them onto a single chip, again increasing our communication rate.
