This paper describes novel transconductor and an integrator circuits which can be used in integrated video frequency filters in bipolar technology. The transconductor consists of a parallel connection of a passive nominal transconductance and an active variable transconductance, resulting in good high frequency performance up to 70 MHz and less than 1% linearity error for input signals up to 2V...
in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa) all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...
The distributed generation (DG) systems based on the renewable energy sources have rapidly developed in recent years. These DG systems are powered by micro sources such as fuel cells, photovoltaic (PV) systems, and batteries. The micro grid concept consists of two stages, in the first stage the low level voltage from the pv cell is converted to high level voltage by using DC-DC converter. In th...
This study presents a Ka-band direct-conversion receiver using 28-nm CMOS (Complimentary Metal Oxide Semiconductor) process for radar applications. The designed includes LNA (Low-Noise Amplifier), Mixer, and Baseband amplifier. adopts two-stage cascode amplifier structure. Then, the mixer is single-balanced passive with low flicker noise. At end, baseband transimpedance fat FET (Field-Effect-tr...
The injection of a seed in a free-electron laser (FEL) amplifier reduces the saturation length and improves the longitudinal coherence. A cascaded FEL, operating in the high-gain harmonic-generation regime, allows us to extend the beneficial effects of the seed to shorter wavelengths. We report on the first operation of a high-gain harmonic-generation free-electron laser, seeded with harmonics ...
A single stage wideband amplifier based on an AlGaN/GaN HEMT power cell with a total gate-width of 16 mm matched to 50 Ohm has been successfully developed and characterized by use of a single-carrier W-CDMA signal. A very wide bandwidth of more than 1.7 GHz covering several mobile radio frequency bands within Land S-band with peak output power levels up to 44 dBm has been demonstrated with meet...
A number of techniques have recently been described to linearize integrated optic intensity modulators, and thus significantly reduce the two-tone intermodulation distortion. The resulting intermodulation distortion produced by these extended linearity modulators then varies as the input power to the fifth-order or higher. When these modulators are included in a fiber-optic link system, the ove...
Introduction: Ultra-high capacity optical interconnection networks are considered as a potential solution to the immense processormemory access communications bottleneck, which is expected to dominate high-performance supercomputers [1, 2]. Optical packet switching fabrics have the potential to supply this next-generation technology with the performance characteristics necessary for efficient c...
