The phase difference and output capacitances of the carrier and peaking PA are analyzed and compensated accurately in a wideband. Thus a sufficient load modulation of the DPA is obtained in a broadband. To verify the proposed design methodology, a broadband high-efficiency DPA MMIC is designed and fabricated in a 0.25 µm GaN-HEMT process for 5G massive MIMO applications. The measurement results illustrate that power added efficiency (PAE) is 44.8%-52.2% at the saturated output power (Psat) of 39.8-40.8 dBm, the PAE at 6-dB output back-off (OBO) is 40.9%-43.9%, and the small-signal gain is 12.5-13.9dB. The proposed DPA demonstrates state-of-the-art saturated and 6-dB back-off PAE among published C-band broadband GaN MMIC DPAs.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135560180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-maximum suppression (NMS) algorithm, as a key component in traffic object detection algorithms, is an independent post-processing process in the object detection framework. Due to the complexity of real-world road scenarios and high density of detected entities in urban traffic, the number of candidate bounding boxes generated by the neural network is large. Hence, low-precision processors may generate a significant number of redundant target bounding boxes. The excessive output of redundant target bounding boxes not only imposes a workload on subsequent processing but also has the potential to result in non-optimal decision-making. We propose a high-performance NMS processor that can quickly process a large number of candidate boxes without performing sorting of their scores. Also, it has low precision loss computing units and high parallel computing arrays. Combined with algorithm design, it effectively reduces the computational complexity and reduces the inference time of the end-to-end task of the NMS algorithm. Thus, our NMS processor’s speed is comparable to SOTA architecture, and the average accuracy loss is only 0.4% .","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135159065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, elongated heating region called backward heating distributes around the feeding line, and potentially causes undesirable heating to non-targeted, normal tissue. In order to suppress the backward heating, we considered use of a sleeve with microwave device. Large sleeve inner diameter is required to use the sleeve effectively. However, small sleeve inner diameter is preferable for use in surgery. In this study, numerical analyses were performed to investigate the optimum sleeve inner diameter. The results indicated over 4 mm inner diameter could suppress the backward heating.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
