  1. 2015/02, Wireless Transceiver Circuits: System Perspectives and Design Aspects, Modern transceiver systems require diversified design aspects as various radio and sensor applications have emerged. Choosing the right architecture and understanding interference and linearity issues are important for multi-standard cellular transceivers and software-defined radios. A millimeter-wave complementary metal–oxide–semiconductor (CMOS) transceiver design for multi-Gb/s data transmission is another challenging area. Energy-efficient short-range radios for body area networks and sensor networks have recently received great attention.

  2. 2015/07, Current Millimeter-Wave Technology, 波長が1cm以下の電波であるミリ波に関する技術開発は長い歴史を持っているが、車載レーダや固定無線などの一部の用途を除いては未だに大きなマーケットを形成していない。 　その原因は、デバイスが未成熟であったこと、ミリ波は直進性が強くこれまでの無線通信とは異なり自由に接続できないこと、ミリ波通信では数Gbpsの超高速データ伝送が可能だが、コストに見合った用途やコンテンツが未成熟だったことなどが挙げられる。 　初期のミリ波デバイスはインパットダイオードやガンダイオードなどの二端子デバイスであった。私が学生だった時代から使用されていたので、40年以上の歴史がある。しかしながら、二端子デバイスは入出力の分離が困難なため応用分野が限定され、ミリ波帯で広く使用されたのは三端子デバイスであるGaAs化合物半導体トランジスタであった。 　現在では、これを伝送線路などの受動素子と併せて集積化したマイクロ波モノリシック集積回路(MMIC)によりミリ波回路の実用化が図られ、衛星放送の受信機、車載レーダ、固定無線などに用いられている。しかしながら、来たる大量使用に向けてモノリシック集積回路による実現が試みられるようになった。当初はSiGeヘテロ接合トランジスタによる集積回路が開発され、続いて微細化により周波数特性が急激に上昇したCMOS集積回路が開発された。CMOS集積回路の意義は高周波性能が目標に達したということだけではなく、デジタル回路との混載が可能であり、ミスマッチの抑制など様々なデジタル補償を用いることで、システム全体の性能向上、小面積化、低電力化が図り易いことや、将来のベースバンド回路との一体集積が可能となることにある。 　また、最近は変復調の多値化ビット数の向上により、同一周波数帯域を用いてもデータレートを向上できる技術が開発されるようになり、従来に比較して約6倍の速度向上が図られている。このためには位相雑音の低減、周波数特性のフラットネスの向上、ベースバンドを含めた雑音や歪の低減が重要である。更にミリ波の課題である直進性への対応として、電子ビームフォーミング技術の開発が盛んである。また、低電力である程度の距離の通信を可能にするためには高利得アンテナが重要となるが、平面アンテナを中心として各種のアンテナ技術や、アンテナとチップを繋ぐ、低損失のパッケージ技術なども開発が進められている。 新たな市場への対応として、超高速データ伝送特性を用いて短時間のデータ伝送特性を実現する、データキオスクなどの新たな近距離無線技術が実用化されようとしている他、光ファイバーに比べて敷設の自由度が高いミリ波無線ネットワーク、4K・8Kなどの超高精細TVシステムへの適用技術、ミリ波イメージング技術なども開発が進められている。 　以上のようにミリ波技術はデバイス技術だけでなく、回路技術やシステム技術の開発により、その課題を克服し、本来の利点である超高速信号伝送の実現に向けた開発が続けられており、今後の無線通信における通信容量の逼迫を解決する技術としてミリ波技術が実用化される日もそれほど遠くないものと思われる。, 2015, 7, 日, 978-4-7813-1078-7, 220, 8

  2. Terahertz CMOS Electronics for Future Mobile Applications , Minoru Fujishima, 225th ECS Meeting, 2014/05/12, With Invitation, The Electrochemical Society, Orland, The highest operation frequency of RFCMOS circuits has risen exponentially over the years. This improved performance has culminated in new wireless and wireline communication standards with higher data rates. There has been a tenfold increase in the wireless data rate every four years, being much faster than the increasing speed of wireline communications. If this trend is to continue, 100 Gb/s will be realized around 2020. In order to realize a terahertz CMOS transceiver with 100 Gb/s, not only is device performance improvement through miniaturization important, but also circuit design techniques that move the circuit operation frequency close to fmax must be developed. Furthermore, one has to remind that stringent practical issue, power consumption, still remains for mobile applications even if the terahertz transceiver is technically feasible. Namely, one must consider how the power consumption maintains at the level of the current mobile applications even when ultrahigh data rate is acquired. This challenging issue implies that the near-fmax design technique is extremely useful because the fmax of a given MOSFET is a function of bias voltage, and reduced-fmax circuits can have superior power efficiency. To utilize near-fmax technology, firstly, one has to know the optimum bias point giving maximum operation frequency under limited power consumption. To achieve low-power operation at a high operation frequency, it is important to choose an appropriate set of bias voltages. The FP (frequency-power) plot is a useful guide to choosing such a set, which shows the gate and drain bias dependences of fmax and power consumption per unit gate width of an NMOSFET. The power-efficient bias points can be found from the FP plot as the points on the power contours where fmax is maximized. The power-efficient bias points give the best fmax for the given power consumption. Since the highest possible fmax of a given MOSFET is realized away from the power-efficient bias points, it is best to avoid the bias point that maximizes the transconductance (gm) if power efficiency is an important design goal. By reducing the actual fmax to be used through tracing the power-efficient bias curve, power consumption can be reduced considerably. As can be observed in 65- and 40-nm CMOS processes, reducing fmax enables exponential power reduction, where the reduction rate is 1/10 every 75 GHz in both process technologies. When trying to obtain the highest possible performance of a MOSFET, the MOSFET must be biased such that its highest fmax is realized. If, on the other hand, the power consumption is a great concern in a terahertz mobile application, one can opt for a reduced-fmax design. Power-efficient bias points can be found in the FP plot. Continued improvement of the device performance is thus essential for achieving the ultimate low-power high-speed wireless communication even in mobile application.
