Thanks to a low-loss novel chip interconnect, based on spray coating of low dielectric permittivity materials, the use of waveguide split-blocks is avoided, reaching a wideband, low-loss and cost-effective solution.","PeriodicalId":6746,"journal":{"name":"2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"67 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2020-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91116675","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}

Three detectors biased at different body voltages are connected in parallel to the antenna, based on that the transistor has the highest voltage responsivity at the subthreshold region. The outputs are current-combined at the transconductance stage of the preamplifier for canceling the leakage signals. The complete detector IC consists of a detector core, a preamplifier, a main amplifier with a folded cascade structure, a biasing circuit and a differential integrated patch antenna. The proposed structure was fabricated with an area of 2.05 mm2using TSMC 0.25-μm CMOS technology. Post-simulation and measurement results show a wide dynamic range and high sensitivity compared to the detector using three equivalently biased transistors.","PeriodicalId":6746,"journal":{"name":"2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"32 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2020-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91229246","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}

Here, the charge carrier dynamics of tin based metal halide perovskite is investigated using optical pump-terahertz probe (OPTP) spectroscopy.
