In the conventional retinal experiments, it is inevitable to flatten the retinal tissue from its original hemispherical shape to form tight attachment to conventional planar electrode arrays or substrates. In the process of deforming the tissue, the retina is subject to mechanical stress, which may cause abnormal physiological reactions. To solve this problem, we present an innovative hemispherical MEAs with a curvature so that the retinal tissue can closely attach to the electrodes without deformation. The proposed MEAs is composed of non-toxic aluminum (A1) foil and elastomeric PDMS substrate. In addition, the fabrication is performed using a simple and inexpensive process. It is expected to stably record the retinal responses from multiple retinal ganglion cells around the optical disc because of the uniform adhesion while maintaining the original shape of the retina.","PeriodicalId":271345,"journal":{"name":"2020 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124821980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SNN, unlike ANN, receives a series of binary-coded spike trains as input and updates the membrane potential of the neuron and generates spikes over a period of time specified by the number of spike trains. The function that generates the spike corresponding to the activation function of the ANN is not differentiable, which makes it difficult to apply the backpropagation (BP) algorithm used in the ANN. In order to overcome this problem, studies using numerical approximation of derivatives have been carried out in various ways. However, research on the decay coefficient and the number of spike trains, which are characteristic of SNN neuron, are insufficient. In this paper, we analyze the distribution of spikes and discuss how the decay coefficient characteristics of neurons and the number of spike trains affect network performance.","PeriodicalId":271345,"journal":{"name":"2020 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125572907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To prevent and be well prepared for extreme events, advanced circuit designs reliable under harsh conditions are necessary. Successive approximation register (SAR) analog-to-digital converter (ADC) has advantages in regards to low power consumption and simple structure compared to any other types of ADCs. Various schemes of calibration for nonlinearity issues are reducing capacitor sizes. The main purpose is to design SAR ADC that sustains performance under radiating environments by optimizing sizes of MOSFETs. In the conference presentation, the proposed Successive Approximation Register Analog to Digital Converter size optimizations and layout for robust-to radiation device will be discussed with initial simulation results. General aspects of the circuit are left unchanged, only simple modifications have been made, thus easily adaptable to radiation hardening applications.","PeriodicalId":271345,"journal":{"name":"2020 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127959799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design extracts jitter from asynchronous type ring oscillator for enhanced randomness.

The design utilizes fewer resources yielding hardware redundancy and enhances the level of randomness. This TRNG has been designed and validated using Artix-7 FPGA. Power dissipation and speed have been obtained as 0.5mW and 138 Mbps respectively. The generated random bit stream has also been sampled and converted to a binary format in MATLAB and tested through the DIEHARD statistical test suite for validation.

The proposed method classifies nine photographic compositions for captured images, and enhances aesthetic quality of the images classified to one of nine compositions. Then, aesthetic scores are measured for the enhanced images to determine that the image is able to be a good photo.

Adding to that, an optional contrast enhancement step could be applied concurrently to further enhance the image.
