Simultaneous switching output buffer (SSO) noise and impedance of power distribution network (PDN) for a 3D systemin package (SiP) with 4k-IO widebus structure has been investigated. The 3D SiP consisted of 3 stacked chips and an organic interposer. These three chips were a memory chip on the top, a silicon interposer in the middle, and a logic chip on the bottom. The size of each chip was the same,...
The electromagnetic noise generated by terahertz photoconductive emitters was investigated, and the intensity of noise spectrum was analysed by statistical method. The relationship between the noise of the emitter and the resistivity as well as carrier lifetime of the antenna material was obtained. And the effect of carrier lifetime and mobility of antennas on the THz generation efficiency was investigated.
We evaluate the optical communication performance of individual comb lines generated in silicon nitride microresonators. A high coherence mode yields error-free communications at 10 Gb/s, while a partially coherent mode results in closed eye diagrams.
This paper describes the industry's first heterogeneous Stacked Silicon Interconnect (SSI) FPGA family (3D integration). Each device is housed in a low-temperature co-fired ceramic (LTCC) package for optimal signal integrity. Inside the package, a heterogeneous IC stack delivers up to 2.78Tb/s transceiver bandwidth. The resulting bandwidth is approximately three times that achievable in a monolithic...
We present a very compact analog-to-digital convertor (ADC) for use as a standard cell. To achieve an inherent accuracy of at least 12-bits without trimming or calibration, extended counting A/D-conversion is used. Here, the circuit performs a conversion by passing through two modes of operation: first it works as a 1st-order incremental convertor and then it is reconfigured to operate as a conventional...
A 2GHz wide input dynamic range (25%–75%) duty cycle corrector (DCC) circuit with ±2% output duty cycle accuracy is presented. This DCC circuit supports input frequency ranging from 1GHz to 2GHz. The proposed circuit is implemented in 45nm low voltage (0.9V to 1.4V) digital CMOS process. Presented DCC consumes only 1.4mW and occupies 0.01 mm2 area. Built-in-self test method is used to test this circuit...
Microarrays represent a new technology for measuring expression levels of several genes under various biological conditions generating multiple data. These data can be analyzed by using biclustering method which aims to extract a maximum number of genes and conditions presenting a similar behavior. This paper proposes a new evolutionary approach to obtain maximal high-quality biclusters of highly-correlated...
It is very difficult to detect the small target over water in the marine environment because of the complexity of water movement and the complex physical fields produced by the water interact with environment. We mainly study foreground segmentation for small target in visual image based on MRF (Markov Random Fields). A foreground segmentation method is proposed that is based on kernel function and...
3D integration technology, especially TSV (Through Silicon Via) based 3D package is a feasible solution for high density and high performance system. The TSV provides a vertical interconnection with a much shorter electrical delay between dies. The EMI (Electromagnetic Interfere) issue draws great attention due to the short vertical distance between noise source circuit and sensitive circuit. In this...
In this paper, silicon Hall sensors with different sizes and doping levels are fabricated. Based on Hall cross prototypes, dependencies of device sensitivity, 1/f noise on doping are investigated. It is found that sensitivity is inversely proportional to areal concentration (n), and 1/f noise is proportional to n−3/2. By trading off the performances, a reasonable higher doping is proved to be preferred...
Decoupling capacitors are widely used in power delivery network (PDN) design to mitigate switching noise from the integrated circuit (IC). Besides, they also provide a low-impedance path to shunt the transient energy to ground at the IC source. Since a real capacitor includes both parasitic inductance and resistance associated with the interconnection and package of the capacitor resulting in an increase...
Backside preparation techniques have advanced to provide reliable IC performance for bulk silicon as thin as 10µm and less (here called moderately thin=MTSi). This opens many doors for optical localization techniques as photons > 1.1 eV can be detected through backside. Now, Si and InGaAs detectors can be compared directly for photon emission (PE) and this paper investigates in depth what is important...
In the state-of-the-art video-based smoke detection methods, the representation of smoke mainly depends on the visual information in the current image frame. In the case of light smoke, the original background can be still seen and may deteriorate the characterization of smoke. The core idea of this paper is to demonstrate the superiority of using smoke component for smoke detection. In order to obtain...
In order to solve the selection of effective singular values, first the characteristic of the singular values of both ideal signals and noise signals was analyzed, a determination method of least squares error was proposed. Then the impact on signal de-noising by analyzing different number of singular values, indicated that the number of effective singular values were accurate and reliable by using...
Stroke has become a very prevalent disease, especially in elder people. Many researches have focused on developing advanced and intelligent robotic system to assist the treatment of patients. For this field, Electromyography (EMG) is widely used for its benefit to get valuable information about the neuromuscular activity of a muscle. In this paper, wavelet packet decomposition method which is a kind...
Random Telegraph Noise (RTN) has been shown to surpass random dopant fluctuations as a cause for decananometer device variability, through the measurement of a large number of ultra-scaled devices [1]. The most worrisome aspect of RTN is the tail of the amplitude distribution - the limiting cases that are rare but nevertheless wreak havoc on circuit yield and reliability. Since one cannot realistically...

We summarize several lines of investigation of foundry-processed patch-antenna-coupled Si MOSFETs as plasmonic detectors of THz radiation. First, we explore detection at frequencies as high as 4.3 THz, about one hundred times higher than the transit-time-limited cut-off frequency of the devices, searching for the fundamental limits of the detection principle. Then, we address the much-debated issue...
The New Energy and Industrial Technology Development Organization (NEDO) advertised for consignment research business called “Verification of Grid Stabilization with Large-scale Photovoltaic Power Generation Systems” in 2006. Two sites were selected for the verification tests, which were Hokuto City in Yamanashi Prefecture and Wakkanai City in Hokkaido. Mega-solar system (Large-scale photovoltaic...
