A Push-Pull Buffer (PPB) is proposed to drive the pass transistor. The low output resistance of the PPB allows the pole at the gate of the pass transistor to be pushed beyond the unity-gain frequency of the LDO regulation loop. Transient response is improved, the settling time of LDO are $0.2mu mathrm{S}text{@} mathrm{C}_{mathrm{L}}=0mathrm{p}$F and $1.14mu mathrm{S}text{@}mathrm{C}_{mathrm{L}}=100mathrm{p}$F. The input transistors of error amplifier are realized Cascode structure which is used for connecting compensation capacitor Cc. With this structure, RHP zero generated by compensation capacitor is pushed beyond the unity-gain frequency of the LDO regulation loop. And LHP zero generated by the Cc is used to compensate the non-dominate poles. Compensation capacitance is 1pF. The Dynamic Transient Improvement (DTI) circuit is adopted to reduce the ripples of the output voltage of LDO. The proposed LDO can operate from a supply voltage of 2.2V-4V with a minimum dropout voltage of 0. 2V at a maximum 50mA load and quiescent current of 70$mu$A. Only 4pF capacitor is integrated in the chip, the output of LDO can be connected 0- 100pF off-chip capacitor.","PeriodicalId":183887,"journal":{"name":"2019 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC)","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133538006","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 image of the cell collected by the medical microscope is segmented into a single white blood cell image with a resolution of 90 × 90 by image threshold segmentation algorithm, and then downsample it to 9 × 9 and input it into the feature fusion network for training. After the training is converged, a feature fusion model is obtained, and then the white blood cell image collected by the lensless cell collection system is input into the model to synthesize the fused cell image with a resolution of 36 × 36. Further, using image binarization and other algorithms, the nucleoplasmic ratio of the fused cell image can be obtained. Finally, the simulated vacuolar white blood cell image with a resolution of 9 × 9 is mixed with the normal white blood cell test image in different proportions and then tested. The test results show that the fused cell image shows a similar topographical feature to the larger part of the mixed test images. This is of great significance for the diagnosis of medical diseases.","PeriodicalId":183887,"journal":{"name":"2019 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126247321","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}
