Increasing data rates of high speed serial interfaces forces the insertion loss and common mode (CM) noise requirements to be tighter. This paper addresses both of these challenges by introducing a new low-loss transmission line design with simultaneous common mode filtering property. The line is composed of periodical repetitions of narrow and wide sections, which generates a CM impedance contrast to filter out the CM noise, while differential impedance is kept constant by locally voiding the planes below and above the wide trace sections. As a result of the wider sections, the loss is also smaller.

Evaluation of Terahertz Channel in Data Centers MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29) Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
Linearization of RF power amplifiers with memoryless baseband predistortion method Kolcuoğlu, Turusan; Demir, Şimşek; Department of Electrical and Electronics Engineering (2011) In modern wireless communication systems, advanced modulation techniques are used to support more users by handling high data rates and to increase the utilization efficiency of the limited RF spectrum. These techniques are sensitive to the nonlinear distortions due to their high peak to average power ratios. Main source of nonlinear distortion in transmitter topologies are power amplifiers that determine the overall efficiency and linearity of the transmitter. To increase linearity without sacrificing effi...
Hybrid control algorithm to improve both stable impedance range and transparency in haptic devices Baser, Ozgur; Gurocak, Hakan; Konukseven, Erhan İlhan (2013-02-01) An ideal haptic device should transmit a wide range of stable impedances with maximum transparency. When using active actuators, transparency improvement algorithms tend to decrease the range of attainable impedances. Passive actuators can transmit high impedances stably, but are not sufficient alone for transparency. In this study, a hybrid force control algorithm employing active and passive actuators was developed to improve the stable impedance range and transparency in haptic devices. A new transparenc...
Design and realization of broadband instantaneous frequency discriminator Pamuk, Gökhan; Yıldırım, Nevzat; Department of Electrical and Electronics Engineering (2010) n this thesis, RF sections of a multi tier instantaneous frequency measurement (IFM) receiver which can operate in 2 – 18 GHz frequency band is designed, simulated and partially realized. The designed structure uses one coarse tier, three medium tiers and one fine tier for frequency discrimination. A novel reflective phase shifting technique is developed which enables the design of very wideband phase shifters using stepped cascaded transmission lines. Compared to the classical phase shifters using coupled ...
Design of a Re-configurable dual frequency microstrip antenna with integrated RF MEMS switches Onat, Sinon; Ünlü, Mehmet; Alatan, Lale; Demir, Şimşek; Akın, Tayfun (2005-07-08) The complete design of a re-configurable dual frequency antenna structure, including its integrated RF MEMS switches and their actuation lines together with a CPW feed, is introduced. The number of switches used in the inset is decreased compared to the hybrid design we presented previously (Onat, S. et al., IEEE Int. Antennas and Propag. Symp., vol.2, p.1812-15, 2004). Instead of utilizing available RF MEMS switches, new switches suitable for this application are designed. Two different switch configuratio...
