Part II, Integrated Filters, presents papers which detail nearly all known techniques to construct integrated filters. These filters all use resistors and capacitors to obtain the filtering function due to the low quality of inductors in silicon. Integration of the filtering function on chips is important to reduce system cost and provide greater accuracy. Part III, Smart Power, illustrates up-to-date techniques for implementing thermal detectors and protection networks to improve reliability and the lifetime of many analog devices.
These devices are more specifically those with different analog blocks operating at different temperatures. Smart Power is thus never limited to circuit design only, but must also include packaging and cooling considerations; it is system design. This approach gives an advantage over the commercial converters tested on the same harvester in terms of efficiency, as well as a possible flexibility in the power monitoring and management.

The ISE Michel S. Two important discussions seem to continue. He is author and co-author of more than scientific papers and holds several patents. His graduate work dealt with the design of a hybrid, integrated, analog signal processor IC for disk drive servo systems. Then, a partitioning exploration introduces parallelism using a cyclo-static dataflow model that also expresses implementation-specific aspects of communication channels. To formulate an approach to CMOS design optimization, experimentally observed analytical relationships showing strong dependences between threshold voltage shifts and silicon dioxide thickness are utilized.
This paper introduces a cascading technique for monolithic switched-capacitor DC-DC converters with a high voltage conversion step. With this technique, the converter is divided into subconverters, each with a low voltage rating. A cascade topology that converts an input voltage of 7. As a result, the proposed design achieves the best high-density figure of merit compared to the state-of-the-art.
The start-up is a critical part for supply voltage generation of integrated circuits. Especially ICs utilizing multiple voltage rails demand a careful consideration of the start-up. This task is generally fulfilled by a power management unit PMU which, despite the increasing integration level, still is mostly implemented discretely.
This paper proposes an integrated PMU generating three different supply voltages, featuring one buck converter to efficiently generate the most energy consuming supply. The start-up of the PMU is considered and the functioning is verified by measurement results. Maximum battery runtime and low power dissipation are the key points for energy harvesting devices development. Therefore, an accurate battery model, describing the static and dynamic battery behaviour, plays an important role in estimating battery state over time and in a wide range of operating conditions.
Simulation and results are discussed, demonstrating the efficiency of the proposed identification method. Fast transient thermomechanical stress to set a pressure-assisted sintering process. High temperature application and long term reliability are the future trends for power electronics.
A key factor to enable future applications is the interconnection durability improvement under high temperature and thermo-mechanical cycling loads. Nowadays, the standard solders cannot fulfill the reliability requirements of future power electronic devices, therefore interconnection technologies have to be developed. One of the most promising joining technique is Ag sintering.
Combining properly temperature, time and pressure, a strong, highly electrically and thermally conductive bond is formed. Different process parameters have been benchmarked by means of physical analyses, performed not only on just assembled devices but also considering the aging effect induced by a liquid-to-liquid thermal shock test. Principal Component Analysis PCA is a widely used method for dimensionality reduction in different application areas, including microwave imaging where the size of input data is large. Despite its popularity, one of the difficulties in using PCA is its high computational complexity, especially for large dimensional data.
However, most of them use manual RTL design, which requires more time for design and development. Our experiments show that the performance of the design obtained with the proposed method is superior to the state-of-the-art RTL design in terms of resource utilization, latency and frequency. It proposes a routing algorithm along with router addressing scheme for BFT topology which can be used in any generic NoC router architecture.

The proposed algorithm has been implemented in software using C, followed by hardware implementation using Verilog. It has been validated using FPGA based hardware and the results show that proposed routing algorithm routes the data from source to destination seamlessly.
This can be incorporated with NoC router architecture to verify several functionalities on a hardware based prototype. Modular multiplication with large integers is the fundamental operation in public-key cryptosystems. The operand size of the multiplier is multiples of bits.
Proposed design consists of 48x48 bit multiplier blocks built from the DSP slices which perform 24x16 bit multiplications and a carry select accumulator built from the DSP slices which perform 48 bit additions. The proposed design first multiplies operands and accumulate the result and then, reduces the accumulated result using Barrett's method.
A Xilinx Virtex-7 implementation of the proposed hardware takes 0. To the best of authors' knowledge, this is the first work which gives the detailed implementation results for full-word Barrett modular multiplier targeting FPGAs with DSP resources. This paper presents a fully parametrized framework, entirely described in VHDL, to simplify the FPGA implementation of non-recurrent Artificial Neural Networks ANNs , which works independently of the complexity of the networks in terms of number of neurons, layers and, to some extent, overall topology.
More specifically, the network may consist of fully-connected, max-pooling or convolutional layers which can be arbitrarily combined. Target of this work is to achieve fast-prototyping, small, low-power and cost-effective implementation of ANNs to be employed directly on the sensing nodes of IOT i. Edge Computing. The performance of so-implemented ANNs is assessed for two real applications, namely hand movement recognition based on electromyographic signals and handwritten character recognition. In this work, a new solution for self-synchronized encryption in physical layer at Gigabit Ethernet optical links is proposed.
Thanks to this structure is possible to encrypt 8b10b Ethernet symbols preserving its coding properties at Physical layer in an optical Gigabit Ethernet interface. The IND-CPA Indistinguishability under Chosen-Plaintext Attack advantage is analysed for the first time concluding that this mode can be considered secure in the same way as traditional encryption modes are.
SDSS-V project is one of the major observational cosmological projects which aims to generate the map of the observable universe by collecting spectroscopic data from the sky using optical fibers. Each optical fiber is attached to a robotic positioner to be automatically coordinated. This paper illustrates the solution to the navigation problem of robotic fiber positioners corresponding to the SDSS-V project.
We note the principal challenging requirements to navigate the robotic fiber positioners. These requirements are those which differentiate the navigation problem of the SDSS-V project from that of the other projects. Then, we discuss the solution in view of both design and implementation. In particular, we specify the hardware and the software components of the solution in a systematic perspective. We illustrate the effectiveness of our solution based on practical results. This article will discuss prerequisites that enable practical EDA solution for analog fault simulation.
It will be shown that a strict and realistic definition set of targets, compliant with emerging IEEE standards for analog test is crucial for the success of such a product. Cadence product for analog fault simulation will be presented and options to mitigate the ever-green problem of analog fault simulation adoption in industrial applications will also be listed. By construction, it should detect any fault i. However, defect-oriented strategies require an evaluation of the test quality prior to their implementation.
This implies resorting to computationally intensive defect simulation campaigns. In this work, we propose an adaptive defect simulation loop that evaluates at each step the defect coverage and the fault escape rate of the test under validation and determines the best way to employ the computational power as a function of the test target metrics.
That is to say, if it is better to simulate the performance setup to update the fault escape metric or, conversely, to simulate the proposed test setup to update the defect coverage metric. Feature selection and feature design for machine learning indirect test: a tutorial review.
Machine learning indirect test replaces costly specification measurements by simpler signatures and use modern learning algorithms to map these signatures to specifications. Defining a set of relevant signatures that appropriately captures the circuit performance degradation mechanisms is then a key point for enabling machine learning indirect test.
