The designed BPF consists of an open-loop resonator on the top layer and defected ground structure (DGS) with a pair of U-shape stepped impedance resonator (SIR) on the bottom layer. The first passband at 2.4 GHz is determined by the SIR-DGS, and the second passband at 5.2 GHz is performed by the open-loop geometry structure. The measured results of the insertion losses are -1.83 dB and -2.4 dB at 2.4 GHz and 5.2 GHz, respectively. The return losses are -38.5 dB at 2.4 GHz and -20.8 dB at 5.2 GHz. The substrate material for fabrication is FR4 with permittivity of 4.4 and the thickness of 1 mm. The total area is 36.9 mm x 11.2 mm.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116148702","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}

Combined high-temperate and low-temperature processes are employed to enable the integration of both n-and p-channel TFTs (N-TFT and P-TFT) on the same piece of single-crystal Si nanomembrane and to enable the compatibility of the device fabrication with the low-temperature plastic substrate. Under a bias voltage (VDD) of 5 V, the inverters exhibit a gain of 5.88 and switching threshold voltage VM of 2.5 V. The high and low noise margins of the inverter are 2.05 V and 2 V, respectively. These demonstrations may eventually lead to low-power digital switching applications using transferable Si nanomembrane on flexible substrates.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124690067","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}

For high speed circuits it is unavailable to drive the SiGe HBT near the breakdown limits. In compact models used for circuit design the breakdown is described by the week avalanche approximation which is unsufficient for modern HBTs with short collector regions. We propose a more refined approximation which is based on the deed space concept for electrons to be accelerated up to the impact ionization energy. The model is implemented in the VBIC compact model.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130447849","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}

These levels are high compared to a full cellular transmit switch product specification of -45 and -40 dBm for 2nd and 3rd harmonics, respectively, at similar power levels.

For the first time we show experimental evidence that drain current noise in weak inversion is indeed shot-like (2ql). In saturation, drain current noise is mainly determined by the drain current, and only weakly dependent on the drain voltage. A simple model of noise is derived and compared with data. The model enables noise estimation from only DC I-V curves, and yields excellent agreement with measurement for PMOS, and acceptable agreement for NMOS.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121599856","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}
