A large number of silicon photonics devices and circuits have been demonstrated in CMOS-compatible fabrication processes. Silicon photonics technologies open up both new opportunities and new challenges to applications, architectures, design techniques, and design automation tools for hybrid photonicselectronics information systems.

The electrical parameters, such as threshold voltage (Vth), drain current (Ids), on-resistant (Ron), sub-threshold swing (SS), and gate leakage current (Ileak) are investigated during the gate stress phase and recovery phase at room temperature. It is found that, during the stress phase, Vth and Ron show positive shifts while Ids show negative shifts. It is because channel electrons are trapped by the dielectric/III-nitride interface layer and by the bulk traps in the gate dielectric. However, these electrical parameter changes cannot be fully recoverable at the end of the recovery phase, followed by 30 mins thermal de-trapping. It may be caused by (1) positive gate bias induced unrecoverable defects in the dielectric layer. (2) bulk trap has a relatively large emission constant. (3) AlGaN barrier exists between the channel and dielectric/III-nitride interface layer, make the electrons hard to exchanges.","PeriodicalId":6737,"journal":{"name":"2021 International Conference on IC Design and Technology (ICICDT)","volume":"13 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76011090","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}

Shock-wave generator techniques are generally divided in voltage-mode and electric current-mode. In voltage-mode, damping RLC circuits are employed to generate mm-wave shock-waves in both parallel and serial configurations. In addition, a positive feedback shock-wave generator to spark an LC circuit and then generate a shock pulse is presented. The circuit does not need any edge-sharpener circuit or over-sized transistors and hence requires a small chip area. Current-mode shock wave generator is presented by a combination of a CMOS excitation circuit and an on-quartz transmission line resonator. Testing prototypes are fabricated, measured, and verified. These proposed shock-wave generators are suitable for transmitter design in low-cost low-power broadband sensing applications.","PeriodicalId":6737,"journal":{"name":"2021 International Conference on IC Design and Technology (ICICDT)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77309534","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}

It has great potential to bypass the limitation of Moore’s law and overcome the inherent bandwidth bottleneck in electronics enabled by the >10 THz wide optical telecommunications band. One of the main challenges for the realization of ONNs is how to avoid practical errors, including various device parameter errors during fabrication and the limited phase shifter control precision. Characterization of each individual chip is possible but time-consuming. To address this issue, in this paper, we propose a robust method to train a series of ONN chips with practical errors using the genetic algorithm (GA). The effect of different parameter errors on the data classification accuracy is analyzed, including the errors in phase shifters, coupling coefficient or extinction ratio, optical absorption loss, and photodetection noise. As a proof-of-concept demonstration, a simulated feedforward ONN is implemented to identify a customized dataset with four classes and four uncorrelated features. The simulation results show that our proposed method could increase the average classification accuracy from 86% to 96% for 50 erroneous ONN chips, approaching the ideal ONN accuracy of 99.69% and demonstrating the effectiveness for significant enhancement in training robustness against practical errors.","PeriodicalId":6737,"journal":{"name":"2021 International Conference on IC Design and Technology (ICICDT)","volume":"19 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73823963","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}

In this work, dual-gate TFT with an unisolated top gate directly contacting with IGZO is used to suppress the above stability issues because of its simple fabrication processes. On one hand, increasing the top gate region (or passivation region) is effective to block the moisture absorption; on the other hand, the post-deposition annealing facilitates the formation of an interfacial layer TiOx at the unisolated gate/IGZO back interface. It is found that this TiOx acts as acceptor-like deep-level traps and the TiOx region increases with increasing the top gate region, which is detrimental to the TFT performance and especially the sub-threshold swing and off-current.","PeriodicalId":6737,"journal":{"name":"2021 International Conference on IC Design and Technology (ICICDT)","volume":"124 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90567943","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}
