Furthermore, a technique is proposed to halve the required number of FFTs (IFFTs), reducing their complexity by 29% for a 32-point resolution; a method is proposed to correct tilt and stretch distortion; and a gain controller with adaptive loop coefficients is adopted to achieve the same stability but 65% higher tracking bandwidth regardless of the FFT size. The concept is validated at the system level, where impairments are applied, enabling an in-depth comparison to conventional discrete multi-tone signalling. Assuming a 32-point FFT, a \u0000<inline-formula> <tex-math>$35dB$ </tex-math></inline-formula>\u0000 channel, and an overlap factor of 3, results show 101% improvement in capacity, 100% improvement in power efficiency, and 101% improvement in area efficiency, and all while maintaining comparable latency.

To support the data rate of 200 Gb/s, orthogonal frequency division multiplexing (OFDM) has been studied recently as one of the possible modulation schemes in the next-generation serial links. The OFDM can feature high bandwidth efficiency without increasing the equalization complexity, leading to a reduced maximum signal amplitude attenuation and lower required DAC/ADC conversion rates given sufficient DAC/ADC resolutions such that the BER is not primarily limited by the data converters’ resolution. This paper presents system-level modeling results of OFDM-based wireline serial links, with a particular emphasis on the impacts of the fast Fourier transform (FFT) processor’s tap count on the serial link performance. The relationship among the cyclic prefix (CP), FFT tap count, and the link bit-error-rate (BER) are thoroughly explained. The analysis explains that the power consumption of a partially-serial FFT processor improves with a larger kernel FFT size, and simulation results show that the BER performance improves with the FFT size where an optimal CP length exists given the FFT size.","PeriodicalId":93442,"journal":{"name":"IEEE open journal of circuits and systems","volume":"3 ","pages":"134-146"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9827577","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62853299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A TIA based on the proposed technique, designed and laid out in a 16-nm FinFET process, demonstrates a 36% increased in BW, a 19% reduction in input-referred noise, and a 57% reduction in silicon area compared to the conventional TIA with inductive peaking. In the proposed TIA architecture, inclusion of a transformer in the forward path compensates partially for the parasitic capacitances of the inverter and relaxes the transimpedance limit of the conventional TIA. The proposed technique also lowers the input-referred current noise spectrum of the TIA.

In past research, it has been shown that seizures can be detected from electroencephalograms (EEG) with high accuracy using local binary pattern (LBP) encoding. This paper explores applicability of binary HD computing to seizure detection from intra-cranial EEG (iEEG) data from the Kaggle seizure detection contest based on using both LBP and power spectral density (PSD) features. In the PSD method, three novel approaches to HD classification are presented for both selected features and all features. These are referred as \u0000<italic>single classifier long hypervector\u0000, \u0000<italic>multiple classifiers\u0000, and \u0000<italic>single classifier short hypervector\u0000. To visualize the quality of classification of test data, a \u0000<italic>hypervector distance\u0000 plot is introduced that plots the Hamming distance of the query hpervectors from one class hypervector \u0000<italic>vs.\u0000 that from the other. Simulation results show that: \u0000<italic>1)\u0000. LBP method offers an average 80.9% test accuracy, 71.9% sensitivity, 81.4% specificity and 76.6% test AUC whereas the PSD method can achieve an average of 91.0% test accuracy, 81.8% sensitivity, 92.0% specificity and 86.9% test AUC. \u0000<italic>2)\u0000. The average seizure detection latency is 2.5s for LBP method and is 4.5s for the PSD methods. This average latency, less than 5s, is a relevant parameter for fast drug delivery, indicating that both LBP and PSD methods are able to detect the seizures in a timely manner. The performance using selected PSD features is better than that using all features. \u0000<italic>3)\u0000. It is shown that the dimensionality of the hypervector can be reduced to 1, 000 bits for LBP and PSD methods from 10, 000. Futhermore, for some approaches of selected features, the dimensionality of the hypervector can be reduced to 100 bits.","PeriodicalId":93442,"journal":{"name":"IEEE open journal of circuits and systems","volume":"3 ","pages":"59-71"},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9744111","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62852816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
