For the first time, an innovative update scheme that enables selective updating without requiring additional transistors is demonstrated. This approach is experimentally validated through an all-InGaZnO (IGZO) thin-film transistor (TFT) 3-transistor 1-capacitor (3T1C) synaptic circuit. IGZO TFTs are specifically chosen for their ability to extend retention times due to extremely low leakage currents and their simplified fabrication processes at low temperatures. Fundamental synaptic operations, including controllable weight updates, long data retention, and stable programming endurance, are confirmed experimentally. Additionally, optimizing operational voltage conditions improves weight update behavior, which enhances network training performance. System-level analysis using a neural network hardware simulator with a derived weight update model demonstrates high training accuracy on the MNIST handwritten digit dataset and achieves maximum accuracy over 98%. With the proposed selection method and tunable weight updates, 3T1C synaptic circuit is a promising candidate for scalable large-scale deep neural network accelerators based on analog compute-in-memory technology.","PeriodicalId":13210,"journal":{"name":"IEEE Journal of the Electron Devices Society","volume":"13 ","pages":"510-515"},"PeriodicalIF":2.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11026025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, two novel configurations are proposed to enhance the classic single-diode model: one adds a diode between the terminal connections, while the other inserts a diode and resistor in series between the same terminals. Second, original analytical expressions for the current-voltage (I-V) characteristics of each proposed circuit are derived using the Lambert W function. Third, the performance of these models is rigorously evaluated on a variety of solar cells under diverse environmental conditions. Results demonstrated the models’ accuracy and robustness, with Root Mean Square Error (RMSE) analysis showing superior alignment between simulated and experimental I-V curves compared to existing single-, double-, and triple-diode solar cell models from the literature. Finally, the proposed approach enhances the mathematical precision in modeling solar cell behavior and provides a reliable framework for optimizing solar energy systems, contributing to improved performance and efficiency in practical applications.","PeriodicalId":13210,"journal":{"name":"IEEE Journal of the Electron Devices Society","volume":"13 ","pages":"501-509"},"PeriodicalIF":2.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11020651","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SenseFET technology, where a current sensor is monolithically integrated with a power transistor, has been widely used in power ICs due to its high precision and low cost. However, for a gallium nitride (GaN) lateral power device in multi-finger configurations, the non-uniform temperature distribution hinders its application in high-precision scenarios. This paper aims to address this issue through a design method of SenseFETs based on a lumped parameter electro-thermal network (LPETN) model. Based on the proposed model, the time-dependent temperature and conduction current distribution are obtained, and the optimized finger selection for the accurate current sense is performed. The thermal network part of the model is validated by the finite element method (FEM) results, and the electrical part is validated through LTSPICE simulation. Finally, taking a 50-finger GaN high electron mobility transistor (HEMT) device as an example, this model is used to select the fingers of a SenseFET for current sensing. Compared with the traditional method, the proposed approach significantly improves the accuracy of the SenseFET, which demonstrates its effectiveness.","PeriodicalId":13210,"journal":{"name":"IEEE Journal of the Electron Devices Society","volume":"13 ","pages":"414-421"},"PeriodicalIF":2.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974612","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
