Nanoelectromechanical systems (NEMS) hold promise for a number of scientific and technological applications. In particular, NEMS oscillators have been proposed for use in ultrasensitive mass detection(1,2), radio-frequency signal processing(3,4), and as a model system for exploring quantum phenomena in macroscopic systems(5,6). Perhaps the ultimate material for these applications is a carbon nanotube. They are the stiffest material known, have low density, ultrasmall cross-sections and can be defect-free. Equally important, a nanotube can act as a transistor(7) and thus may be able to sense its own motion. In spite of this great promise, a room-temperature, self-detecting nanotube oscillator has not been realized, although some progress has been made(8-12). Here we report the electrical actuation and detection of the guitar-string-like oscillation modes of doubly clamped nanotube oscillators. We show that the resonance frequency can be widely tuned and that the devices can be used to transduce very small forces.

A monolithic phased array using rf mems technology Topallı, Kağan; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2007) This thesis presents a novel monolithic phased array implemented using the RF MEMS technology. The structure, which is designed at 15 GHz, consists of four linearly placed microstrip patch antennas, 3-bit distributed RF MEMS low-loss phase shifters, and a corporate feed network. The RF MEMS phase shifter employed in the system consists of three sections with a total of 28 unit cells, and it occupies an area of 22.4 mm 2.1 mm. The performance of the phase shifters is improved using high-Q metal-air-metal ca...
A novel fault tolerant architecture on a runtime reconfigurable FPGA Coşkuner, İbrahim Aydın; Güran, Hasan; Department of Electrical and Electronics Engineering (2006) Due to their programmable nature, Field Programmable Gate Arrays (FPGAs) offer a good test environment for reconfigurable systems. FPGAs can be reconfigured during the operation with changing demands. This feature, known as Runtime Reconfiguration (RTR), can be used to speed-up computations and reduce system cost. Moreover, it can be used in a wide range of applications such as adaptable hardware, fault tolerant architectures. This thesis is mostly concentrated on the runtime reconfigurable architectures. C...
Implementation of a risc microcontroller using fpga Gümüş, Raşit; Güran, Hasan; Department of Electrical and Electronics Engineering (2005) In this thesis a microcontroller core is developed in an FPGA. Its instruction set is compatible with the microcontroller PIC16XX series by Microchip Technology. The microcontroller employs a RISC architecture with separate busses for instructions and data. Our goal in this research is to implement and evaluate the design in the FPGA. Increasing performance and gate capacity of recent FPGA devices permits complex logic systems to be implemented on a single programmable device. Such a growing complexity dema...
A Thermal and Electro-magnetic Hybrid MOEMS Microscanner with Integrated Spatial Light Modulation and Metalens for Resolution Enhancement of Infrared Imaging Systems Sozak, Ahmet; Simsek, Ertug; Yelboga, Tolga; Gungor, Alper; Balli, Fatih; Azgın, Kıvanç (2022-01-01) IEEEThis article describes the development of a novel integrated thermal and electro-magnetic hybrid micro opto-electro mechanical system (MOEMS) based scanning actuator. Determining the optical architecture and components used for scanning are significant points of the study. A metalens and a coded mask, both of which can be produced by micro fabrication methods, are used in the optical part of the actuator. In this context, a metalens consisting of nano-holes was designed and fabricated as the first alter...
The implementation of a direct digital synthesis based function generator using SystemC and VHDL Kazancıoğlu, Uğur; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007) In this thesis, a direct digital synthesis (DDS) based function generator design module is presented, defined and implemented using two digital hardware modeling/design languages namely SystemC and VHDL. The simulation, synthesis and applicability performances of these two design languages are compared by following all digital hardware design stages. The advantages and open issues of SystemC based hardware design flow are emphasized in order to be a reference for future studies. SystemC initially appeared a...
