Many people predict Internet of Things will become the next big wave of IT industry. Some people predicts there are a trillions of dollars businesses in the IoT era, as IoT will significant improve our lives. However, are energy efficiency VLSI designs critical to the success of IoT? Or, they are just nice-to-have. In this talk, we plan to discuss the following topics: What are the key computing and...
The CMOS PA becomes a reality due to the active research work in recent years. But the performance is not up to the expectation because of the inherent problems of CMOS such as low power density and poor linearity. To enhance the performance further, various adaptation techniques are applied to CMOS PA, i. e. at the gate and drain. In this talk, we will introduce the advanced CMOS PA with the adaptaions.
Electroceuticals are medical devices that employ electrical currents to affect and modify body functions as an alternative to drug-based interventions. In contrast to pacemakers and other classical excitable-tissue stimulators, modern electroceuticals employ sophisticated control strategies that go beyond simple stimulation-response mechanisms in order to modulate physiological regulation loops. Examples...
With the rise of virtualization and cloud computing, traditional networking models do not scale. Software-Defined Networking (SDN) has been labeled a game-changing technology in the data center and is gaining market share in enterprise and service provider environments. In this talk, I will discuss why there is so much interest in SDN, and present different approaches to SDN, ranging from overlay...
Electronics design has been driven by three major trends in recent years: going green, health & safety and connected intelligence. These three trends converge for automotive electronics design, driving the need for energy-efficient, intelligent and reliable chip products. This increases design complexity and demands for higher-quality products. Historically, test of automotive chip products has...
Dark Silicon is predicted to dominate the chip footage of upcoming many-core systems within a decade since Dennard Scaling fails mainly due to the voltage-scaling problem that results in higher power densities. It would deem upcoming technologies nodes inefficient since a majority of cores would lie fallow. International research efforts have recently started to investigate and mitigate Dark Silicon...
With the emergence of bands and combination of bands along with Carrier Aggregation (CA), the mobile handset RF front-end design has become much more complex and is revolutionizing the Front End Industry. While the industry has gone through a dis-integration strategy to reduce the front-end component cost, the industry has seen a change where the integration of the front-end components has shown both...
Electronic innovation is becoming increasingly more important in the evolution of our society. Noble goals of extending healthy lives with improving medical capabilities, creating a cleaner environment, eliminating auto fatalities, and creating a connected infrastructure around the “Internet of Things” all center on electronic innovation. These goals are being driven by both legislation and consumer...
Lower power digital circuits in cellular phones, laptop or tablet computers have critical power consumption limitations. Power consumption at process corners can vary as much as 50%. In order to optimize high-speed logic circuit designs for low power needs, we need to accurately predict device to product aging across process, temperature and voltage corners. In this talk, we focus on the impact of...
Moore's law continues to the engine of growth for the global electronics industry. The understanding of IC degradation mechanisms has resulted in rapid reliability improvements that have enabled the rapid rate technology progression we have experienced. Going forward it is clear that the reliability margins the industry has enjoyed in the past will shrink. The question is now whether reliability will...
Since the first analog cellular system AMPS was commerically introduced in North America in 1978, cellular handsets have evolved from voice-centric entry phone to today's highly sophisticated smart phones that feature unprecedented multimedia experience and enriched user services. Consequently and inevitably, more challenges and higher expectations have been imposed to the development of handset front...
DRAM and NAND technologies have been successfully developed so far thanks to advanced patterning and device technologies, meeting high density, high performance and low cost requirements. However, imminent scaling limit in DRAM and NAND requires breakthrough technologies to meet market needs.
The Internet of Things (IoT) is a trend and not a single sector or market. The most common view is of IoT as a collection of smart, sensor-enabled physical objects, and the networks, servers and services that interact with them. Chip/System designers have to consider many challenges from implementation of sensors chips including, embedded microprocessors through to connectivity via wired or wireless...
Smart sensors are currently demanded in various kinds of applications to pave a way for better life. To reach this goal, it is necessary to provide energy-efficient solutions with analysis capability. Though state-of-the-art SoC's can meet μW-level processing requirements, front-end sensors remain a bottleneck to be solved. In this paper, a few sensors based on event-driven techniques to improve energy-efficiency...
More and more embedded systems are used in safety-critical areas such as automotive electronics and medical applications. These safety-critical applications impose stringent requirements on reliability, performance, low-power and testability of the underlying VLSI circuits. With silicon technology scaling, however, VLSI circuits operate very often at high temperature, which has negative impact on...
This last decade Silicon-on-Insulator (SOI) MOSFET technology has demonstrated its potentialities for high frequency commercial applications, reaching cutoff frequencies close to 500 GHz. SOI also presents the major advantage of providing high resistivity substrate capabilities, leading to substantially reduced substrate RF losses. High Resistivity SOI is commonly foreseen as a promising substrate...
This work reviews transistors of advanced CMOS process nodes from a reliability perspective and covers some of the important challenges and solutions. Physical mechanisms for various modes are investigated for 65nm to 22nm nodes with focus on disruptive changes such as HK/MG and Tri-gate/FinFET. The importance of modeling non-idealities and variation is also emphasized, and projections are made for...
Potential of a cloud system combining a smart device and cloud servers is increasing. One of the representative examples is "Siri" which offers a friendly web knowledge navigator based on natural language user interface. Since latest portable devices equip not only a microphone but also a high resolution camera, this kind of cloud based framework is also promising to create various kinds...
Novel materials and specialty processes are expanding rapidly. Low power high performance devices 3D transistor, packaging and memory drove the demands. Innovation in new manufacturing methods/hardware and new chemistries are required to meet the challenges. Several examples in the past such as Cu metallization evolution and interface cleaning illustrate the efforts how the equipment vendor overcame...
As design becomes more and more complicated, functional verification is getting challenging than ever. The challenges come in twofold: verification is taking longer to finish and difficult to catch all functional errors. Surveys[1] shown that functional error has been the number one reason for re-spin. How well verification is done becomes a very important issue. Re-spin not only can cost a lot due...
