Circuits for Beyond 100Gb/s Wireline Communications

几十年来，微电子的研究和发展产生了更便宜、更快、更可靠的电子产品。今天，电子芯片通过我们的电脑、手机、人体传感器、家庭传感器、家用电器、汽车和道路，构成了我们互联网连接的支柱。今天，微芯片将我们与周围的每个人和每件事联系起来。然而，对更多的渴望远未结束。我们感兴趣的是前所未有的通信速度，传输和接收信息的速度超过每秒1000亿比特（100Gb/s），而每比特的能量和成本只是我们今天所花费的一小部分。本研究的目的是实现这一愿望，并实现超过100Gb/s的可靠数据通信。本研究将探索与微芯片之间通信相关的四个领域的可能性：1。当两个微芯片用铜线连接时，我们将探索信息通信的极限。我们希望找出阻碍通信速度的因素，以便了解哪些速度在理论上是可能的，哪些是不可能的。一旦我们找到了两者的界限，我们就会尝试实现理论上可能的目标。2. 我们探索了每次使用信道时打包更多信息的信令方法，每个符号填充超过一个比特，从而提高了通信的总体速度。3. 我们探索恢复信号的方法，恢复数据，在它消失在噪声中之前，通过这样做，将允许数据走得更远。4. 我们探索了当两个微芯片并排放置时消除导线的方法，而是使用电磁耦合作为可靠的数据通信手段。在这种方法中，我们需要设计电子设备，以可靠地将我们的发射信号发射到线圈上，并在另一端可靠地接收和检测该信号，同时我们将线圈尽可能小，以便将更多的线圈集成到单个芯片上，再次提高我们的通信速率。

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.
