Summary form only given. With the development of information technology, the power supplies for ITs' products have become more and more important. However, the power consumption and standby power losses for IT products such as data centers are increasing, which become a serious problem. Power electronics technologies are promising for energy saving. In this presentation, the market of power integrated circuits will be addressed first. The power losses on power adaptor with full load condition and light load condition are discussed. Finally, a high efficiency single-stage adaptor with primary control and quasi-resonant control is proposed. The experimental results are also provided to verify the performance of the proposed power integrated circuits.

This work presents our verification methodology from architecture to RTL design. There are three major benefits of the proposed verification methodology. First, this methodology enables the verification task to start at architecture design stage even without the implementation details. Second, the verification framework is well-organized and suitable for fully automation. Hence, human-introduced errors can be eliminated and the verification environment can be brought up efficiently. Thus verification engineers can focus on developing scenario to verify the RTL design. The most important one is that this methodology defines a framework for verifying designs at different design stages. In addition, flexibility is also kept for successive refinement of testbench when design state move from architecture to RTL stage. High reusability saves many manual efforts from developing and maintaining different verification environments for different design state. High flexibility makes the verification environment to be easily extended for different design stages.

Summary form only given. Wireless microsensors and other miniaturized electronics cannot only monitor and better-manage power consumption in emerging small- and large-scale applications (for space, military, medical, agricultural, and consumer markets) but also add energy-saving and performance-enhancing intelligence to old, expensive, and difficult-to-replace infrastructures and tiny contraptions in difficult-to-reach places (like the human body). The energy these smart devices store, however, is often insufficient to power the functions they incorporate (such as telemetry, interface, processing, and others) for extended periods. Still more, replacing or recharging the batteries of hundreds of networked nodes is costly, and invasive in the case of the human body. Harvesting ambient energy to continually replenish a battery and wirelessly harnessing radiated energy periodically are therefore appealing alternatives, even if the development of relevant technologies today is, in relative terms, at its infancy. This talk discusses the state of the art and current research efforts in harnessing and conditioning energy and power from miniaturized transducers.

In this work, a design for diagnosability (DFD) method based on observation point (OP) insertion is proposed to improve the diagnosis resolution of transition faults in a circuit. The main objective is to minimize the number of observation points since this number will directly affect the area overhead of the circuit. We develop a novel algorithm to generate a set of OP candidates and then select a minimal number of OPs from this set which can distinguish all targeted fault pairs. An observation point insertion logic is also proposed that can efficiently reuse the output pins in the original circuit so as to reduce the number of extra output pins. In addition, a novel structural distance calculation method for synthesized circuits is proposed that considers the mixed structure of primitive gates and complicated gates, including AOI or OAI gates. Experimental results show that after applying the OP insertion method, all aborted fault pairs can be distinguished and the number of required observation points is quite small. We also use the observation points to distinguish those indistinguished far-away fault pairs. Experimental results show that all targeted fault pairs can be distinguished with a few observation points and a set of diagnosis patterns for ISCAS89 and ITC99 circuits.

This paper presents a timing error resilient flip-flop (ERFF) circuit with high energy-efficiency. The proposed flip-flop design automatically corrects timing errors and therefore minimizes the performance degradation due to variations. The simulation results show that the proposed design can achieve better energy-efficiency in ISCAS'89 benchmark circuits and LEON3 integer-processing unit, when compared to other state-of-the-art timing error detection and correction methods.

This work presents a novel design for input ESD protection. By replacing the protection resistor with an active switch that isolates the input transistors from the pad under ESD stress, the ESD robustness can be greatly improved. The proposed designs were designed and verified in a 40-nm CMOS process using only thin oxide devices, which can successfully pass the typical industry ESD-protection specifications of 2-kV HBM and 200-V MM ESD tests.

This paper presents a Contact Resistive Random Access Memory (CRRAM) macro with an offset-compensated Sense amplifier for low-voltage operation. The proposed circuit aims to solve the variation and speed issues during low-voltage operations. A 256Kb test-chip was fabricated in TSMC 65nm technology. An improvement of 1.78x in read speed and 85.7% in offset was measured compared to conventional sensing methods, and the minimum operating voltage was as low as 0.3V.

Memory is a necessary part of any computing system as it is used to store data as well as programs. The amount of main memory (DRAM) has been increasing for all segments of computing devices to accommodate an ever-increasing number of applications installed and data needed for those applications. Memory used at the microarchitectural level to enhance computing system performance or to reduce system power has been increasing in capacity as well. For example, the total amount of cache capacity as well as the number of levels of cache on a microprocessor chip have been increasing in the last couple decades. As the amount of memory used in a computing system increases, it is important to evaluate design trade-offs in details. In this paper we compare a few evaluation approaches of memory system design and discuss the pros and cons of these approaches.

Summary form only given. Due to various manufacture difficulties in nano-scale semiconductor devices, certain layout patterns cannot be manufactured properly and cause significant yield loss. Due to the time to run through complete lithography simulation, it is impossible to identify all of them before silicon manufacture. Therefore, post-silicon physical failure analysis is needed to find them one-by-one to improve yield iteratively with each re-spin. However, physical failure analysis is time-consuming such that each re-spin can take a long time. To speed-up yield ramp-up, we proposed to automatically identify as many layout patterns as possible by using volume diagnosis from post-silicon manufacture failure data. Typically volume diagnosis uses two procedures. First, responses from failing devices are analyzed using defect diagnosis tools. Next the results of diagnoses are analyzed using statistical, data mining and machine learning techniques to effectively determine the underlying problematic layout patterns. In this presentation, we will discuss the procedures and statistics methods for analyzing diagnosis data and put special attention to the link between defects and layout patterns.

Summary form only given. Cars are increasingly driven by electronics to reduce human error, improve traffic flow and to meet environmental regulations. The semiconductor components that enable this functionality range from medium voltage discretes to replace relays to integrated, high-voltage motor drivers with re-programmability at high temperature. In this talk we will review the technology trends underlying the improvements in power discretes, such as IGBTs and GaN HEMT devices, the scaling trends and integration needs of high-voltage BCD CMOS flows, as well as the adjacent assembly challenges of power devices and power integrated modules.
