This requirement extends from RF power transistors to the power amplifiers (PAs) in which they are employed. As a result, PA designers must find ways to effectively balance the need to achieve the highest PAE with ensuring the resulting RF output signal does not interfere with neighboring signals through spectral re-growth. Techniques including digital pre-distortion and crest factor reduction have been developed to achieve maximum efficiency and dynamic range while minimizing spectral re-growth through high adjacent-channel leakage power (ACLR). This paper describes both techniques, illustrates how the benefits achievable with each one can be effectively determined during the early stages of design, and shows the level of potential improvement using a multi-carrier 3GPP WCDMA HSDPA signal as an example.","PeriodicalId":436457,"journal":{"name":"2008 9th International Conference on Solid-State and Integrated-Circuit Technology","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120841697","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 results show that the devices with channel lengths/widths of 0.45/10 and 10/10 ¿m have flat saturation current. It suggests that there is a requirement for a device to have a channel length of over 0.45 ¿m to provide better sensing characterization to normalized current change. The experimental result also demonstrates the fine linear dependence of stress distribution to the distance of tested devices from the clamping end for a silicon cantilever. The stress distribution is detected via normalized current change for all the three sizes of channel length and for both the n and p- types.

With cyclic HF/DIW cleaning and N2 plasma surface activation, large-area layer transfer of GeOI substrates was realized by ion-cut processes with bulk Ge wafer as the donor wafer. The GeOI substrates are thermally stable up to 550°C annealing and surface roughness can be smoothed down to 0.3 nm RMS by Chemical Mechanical Planarization (CMP). After surface polishing, Epi-Ge on Si wafer can also be used as the donor wafer to realize layer transfer. Four-probe configuration Pseudo-MOSFET was employed to characterize the electrical properties of the transferred Ge and the Ge/SiO2 bonding interface. At Ge/SiO2 interface, GeOI substrates show both accumulation and inversion conduction modes. High-temperature forming gas annealing in the vicinity of 500°C¿600°C has shown the best carrier mobilities, with the interface trap density and interface fixed charge density as low as 1010/cm2.

To ensure the secure information transaction of tags, a scheme of RFID system authentication protocol based on Elliptic Curve Cryptography (ECC) is proposed. However, hardware implementation of ECC processor for RFID tags is a challenge for the requirements of low-power consumption and low-cost chip resource. In the paper we propose a novel ALU architecture for ECC processor on tags. By specially restructured the conventional mathematical expressions of Montgomery algorithm, the ALU operation of point multiplication in our design is reduced by nearly 47%. Also, various multipliers, such as bit-serial multiplier, digit-serial multiplier and the divided algorithm are adopted to balance between power consumption and speed. To attain ultra low power consumption, other techniques, such as finite state machines (FSM) optimization, clock gating, pipelining operations and low-power target library are used in the design. The area of the ECC processor is equal to 16.9 k gates equivalents. It performs an elliptic curve point multiplication in 36174 clock cycles and has a power consumption of 6.607 ¿W at 1.28 MHz using TSMC 0.18 ¿m low-voltage cell library.","PeriodicalId":436457,"journal":{"name":"2008 9th International Conference on Solid-State and Integrated-Circuit Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124617381","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}
