The detailed analysis and design procedures are presented in this paper. To further reduce the chip size, the multilayer metallization above the lossy silicon substrate is employed to implement the hybrid. A V-band down-converted 2× harmonic mixer in 90-nm CMOS process and a D-band down-converted 4× harmonic mixer in the 130-nm SiGe process are designed, fabricated, and measured to verify the concept. The 2× harmonic mixer possesses 0-dB conversion gain at 60 GHz with 0-dBm LO power with merely 2.4-mW dc power. The 4× harmonic mixer achieves 0.5-dB conversion gain at 120 GHz with 2-dBm LO power and 27.3-mW dc power. With the proposed reduced-size 180° hybrid, gate/base-pumped harmonic mixers are very attractive in transceivers demanding low LO frequency and power.}}, author = {{Kuo, Jhe-Jia and Lien, Chun-Hsien and Tsai, Zuo-Min and Lin, Kun-You and Schmalz, Klaus and Scheytt, Christoph and Wang, Huei}}, journal = {{Microwave Theory and Techniques, IEEE Transactions on}}, number = {{8}}, pages = {{2473--2485}}, title = {{{Design and Analysis of Down-Conversion Gate/Base-Pumped Harmonic Mixers Using Novel Reduced-Size 180 ^\circ Hybrid With Different Input Frequencies }}}, doi = {{10.1109/TMTT.2012.2202039}}, volume = {{60}}, year = {{2013}}, } @inproceedings{24343, abstract = {{50 Jahre Moore‘s Gesetz ? „More Moore“ & „More than Moore“ ?

Part of the<br />problem was the lack of diversity of Greek agricultural production, which was focused on raisins and currants (especially flavourful raisins, grown exclusively in the area around Corinth) for export. The collapse of market prices for this good seriously affected the Greek treasury and society in the growing regions. The Greek government responded by trying to withhold part of the harvest in fertile years to stabilise world market prices. Plans to organise a monopoly company for the currant trade necessitated high sums of capital from abroad.

The reflectometer is verified with a circuit breakout including an integrated dummy sensor. The reflectometer is able to measure the phase of the reflection coefficient from 117 to 134 GHz with a resolution of 0.1° and a standard deviation of 0.082°. The integrated sensor with the reflectometer circuit have been fabricated in a 190-GHz fT SiGe:C BiCMOS technology. It spans an area of 1.4 mm 2 and consumes 75 mA from a 3.3-V supply. The circuit has been assembled on a printed circuit board for characterization by immersion into test liquids. The sensor is controlled by a controller board and a personal computer enabling a measurement time of up to 1 ms per frequency point. Functionality of the sensor is demonstrated from 118 to 133 GHz with immersion of the sensor into different binary methanol-ethanol mixtures, showing good correlation between theory and measurement.
