This paper introduces a new design of penternary inverter gate based on graphene nanoribbon field effect transistor (GNRFET). The penternary logic is one of Multiple-valued logic (MVL) circuits which are the best substitute for binary logic because of its low power-delay product (PDP) resulting from reduced complexity of interconnects and chip area. GNRFET is preferred over Si-MOSFET for circui...

A historical sketch of microwave integrated circuits, monolithic microwave integrated circuits, and their application is presented in this paper.

A new generation of high-frequency integrated circuits is presented, which is called substrate integrated circuits (SICs). Current state-of-the-art of circuit design and implementation platforms based on this new concept are reviewed and discussed in detail. Different possibilities and numerous advantages of the SICs are shown for microwave, millimeter-wave and optoelectronics applications. Pra...

the most common type of childhood-onset epilepsy syndrome is childhood absence epilepsy (cae) with well-defined electro clinical features but unknown pathological basis. the incidence of absence epilepsy is about 2 and 8 out of every 100 000 children up to the age of 16, and the prevalence is 2 and 10% of children with any form of epilepsy. children with cae suffer from high rate of pretreatmen...

In this paper, a model for MEMS capacitive microphone is presented for integrated circuits.  The microphone has a diaphragm thickness of 1 μm, 0.5 × 0.5 mm2 dimension, and an air gap of 1.0 μm. Using the analytical and simulation results, the important features of MEMS capacitive microphone such as pull-in voltage and sensitivity are obtained 3.8v and 6.916 mV/Pa, respectively while there is no...

A novel power amplifier unit for a phased array radar with 2 × output ports vacuum electron device is proposed. Double parallel connecting microstrip meander-lines are employed as the slow-wave circuits of large traveling wave tube operate in Ka-band. The high frequency characteristics, transmission and beam–wave interaction processes this simulated optimized. For each port one channel, simulat...

In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...
