The presented CP based on source-switched structure achieves good matching of charging and discharging currents over a broad dynamic range by introducing a novel rail-to-rail operational amplifier. The stable output voltage of the modified charge pump dramatically reduces the jitter of all output clocks in the locking state. Simulation results at a 1.2V supply voltage and a 40 nm COMS technology demonstrate the maximum mismatching ratio of charging and discharging currents decreases from 26.3% to 5.4% over the operating range of 0.2~1V. Furthermore, compared with the conventional charge pump, the maximum reduction magnitude of jitter for the related output clock is as much as 74.3% at the reference input clock of 1GHz.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116608558","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}

Firstly, the scattering point model of the rotor blade echo is used to generate the target echo. Under the condition of different signal-to-noise ratio, time-frequency diagram of the echo with different number of rotor blades is constructed by using short-time Fourier transform, which is used as the test set and training set. Three convolutional neural network models of lenet, alexnet and vggnet are used for training. The performance of the network model is compared, and the recognition performance of the alexnet network model is analyzed under ambiguous, unambiguous and a method of Interpolation to resolve ambiguous. Through experiments, it can be found that the recognition rate of the proposed method can reach 95% under the condition of signal-to-noise ratio of 10dB. It has good recognition performance for classification of rotor blade number, and provides effective data and algorithm support for the rotor target recognition in the future.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"253 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116727424","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}

Deep learning algorithms can learn advanced features from massive data and automatically extract features, which makes deep learning surpass traditional machine learning algorithms. However, as deep learning algorithms rely on large amounts of data and run too slowly, transfer learning arises in response to this disadvantage. Transfer learning allows the use of existing knowledge in the relevant domain to solve a learning problem with only a small number of sample data in the target domain. Combining the two technologies of deep learning and transfer learning, on the one hand, advanced features of data samples can be automatically learned, and on the other hand, it can get rid of the dependence on sample data capacity. In this paper, the electrocardiogram (ECG) signal into spectrogram, and the model is trained with the ImageNet dataset, and then the trained model is transferred, because AlexNet model needs to be fixed image size, so the last pool layer is replaced by a spatial pyramid pooling layer, finally use Softmax classifier for PhysioNet challenge 2017 electrocardiogram data sets are classified, get a 92.84% accuracy and 83.26% F1.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116908651","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 traditional ECG signal denoising technology depends on effective filters, which is artificially created by experience. Once the form of the signal is updated, the inherent space may no longer be suitable for this problem. As the deep learning method can learn sparse features from the data without manual intervention. We designed a deep learning process to apply the powerful functions of neural networks to the inference of the ECG sparse noise reduction model, which can also solve the optimization problem in sparse signal processing. By using this method of deep expansion, an optimization strategy is proposed, which turns the iterative optimization problem into constructing a new network framework. In this way, the model parameters can be easily solved through cross-layer. Through experimental verification, our method improves the SNR by 83.29% compared with the current advanced method.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115006413","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}

Aiming at the Doppler frequency search efficiency of traditional PMF-FFT algorithm, this paper proposes a Quinn-PMF-FFT. Before estimating the Doppler frequency, there is double zero padding, the point of signal does 2N to fill after zero Fourier transform arithmetic, and makes the increase in the number of spectral signal spectrum in the main lobe, then gets more spectral information to modified of the peak position.
