By using four-stage power combination technique at output stage, this new amplifier is able to deliver +32dBm power at input power of •2.7dBm. A PAE (power-added-efficiency) of 48.24% and 15.2% can be obtained at its PO1dB (output 1dB compression point) and +25dBm output power, respectively. A saturated power of +33.5 dBm can be achieved. Powered by a 3.3 Volt DC supply, this proposed power amplifier offers a power gain of 35.8dB. The simulation results show that this design can be fully adopted in 3.5GHz mobile WiMAX subscriber applications.

The most important part to develop the system is to realize sensing components with high sensitivity, high reliability, low power consumption, low noise and small size in a cost-effective way. The Si-nanowire (Si-NW) ion-sensitive field effect transistor (ISFET) has been considered as one of the most promising devices because of the well-established fabrication techniques taking advantage of the low-cost wafer-scale top down methods [1–2]. In this work, the Si-NW ISFETs with embedded Ag/AgCI electrode have been demonstrated. The DC characteristics and the pH response of the Si-NW ISFET were measured and analysed. In addition, the low-frequency noise measurement was performed in order to investigate noise characteristics of the Si-NW ISFETs.","PeriodicalId":6363,"journal":{"name":"2011 IEEE International Conference of Electron Devices and Solid-State Circuits","volume":"47 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81002220","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}

The core/shell nanowire is adopted for the bulk of the device, with source region in the core of the wire and shell for the channel. The tunneling thus occurs in the radial direction, increasing the junction area substantially and leading to large on current. The core-shell junction is made of Ge-Si, and a lightly-doped drain-extension is used to suppress ambipolarity, which impedes the application of many types of tunneling devices in digital circuits. Comparison with unipolar axial-HJ GAA NW-tFET is made to show the advantage of the radial structure.","PeriodicalId":6363,"journal":{"name":"2011 IEEE International Conference of Electron Devices and Solid-State Circuits","volume":"1 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76627504","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}

However, the reduced effective gate voltage due to voltage drop across the underlap lengths also reduces the on-state drive current of the device. To alleviate this trade-off a novel Si3N4: HfO2 dual-k spacer underlap channel DSSB SOI MOSFET has also been proposed. Although the presence of HfO2 inner spacer layer increases the gate capacitance, the reduction in off-state leakage current and the improvement in on-state drive current over the conventional Si3N4: SiO2 spacer overlap/underlap channel DSSB SOI MOSFETs makes the proposed device suitable for low-power digital logic circuits.","PeriodicalId":6363,"journal":{"name":"2011 IEEE International Conference of Electron Devices and Solid-State Circuits","volume":"71 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83373482","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}
