During this study, various narrowband single-ended inductive source degenerated Low Noise Amplifiers (LNAs) for GSM and S-band low earth orbit (LEO) space applications have been designed, simulated and compared using Mietec CMOS 0.7 mu m process and the Cadence/BSIM3v3. To get more realistic results, parasitic effects due to layout have been calculated and added to the simulations. Also, considering the inductive source degenerative topology, most of the attention is given on the modeling of planar spiral inductor by lumped element circuits. Moreover to decrease the substrate effects, the inductors have been surrounded by grounded guard rings and have patterned ground shield (PGS) under them. The simulation results of LNA including the parasitic effects indicate a forward gain of 9 dB with noise figure of 4.5 dB while drawing 18 mW from + 3 V supply at 22 10 MHz. The area occupied is 1.8 mm X 1.6 mm with pads, 1.3 mm X 1.2 mm without pads.

Sensorless control of a three-degree-of-freedom ultrasonic vibration tool holder Gao, Jian; Çalışkan, Hakan; Altintas, Yusuf (Elsevier BV, 2019-07-01) Piezoelectric actuators are commonly used to deliver vibrations with an amplitude range of (5 mu m-25 mu m) at ultrasonic frequencies (>= 15 kHz) in machining applications. The natural frequencies of ultrasonic vibration actuators vary under the varying cutting force disturbances during machining. Consequently, the amplitudes of delivered vibrations deviate from the desired reference values. As opposed to using vibration sensors, this paper presents a sensorless method to track and control the frequency and...
DIRECTIONAL DEPENDENCE OF EXTRAORDINARY INFRARED OSCILLATOR PARAMETERS OF TLGAS2-TYPE LAYER CRYSTALS Hasanlı, Nızamı; TAGIROV, VI (Elsevier BV, 1983-01-01) The directional dispersion of IR-active modes of TlGaS2, TlGaSe2 and TlInS2 layersingle crystals has been investigated, depending on the angle between the phonon wave vector q and the optical c-axis. Owing to the possibility of preparation crystals with various orientations of reflecting surfaces with respect to the optical c-axis, it was of interest to check the applicability of the generalized Born and Huang theory of long-wave optical vibrations in uniaxial crystals to TlGaS2-type layer crystals.
INFRARED REFLECTIVITY SPECTRA OF TLGAS2-TYPE LAYER CRYSTALS Hasanlı, Nızamı; RAGIMOV, AS; TAGIROV, VI; GUSEINOV, RE (Elsevier BV, 1982-01-01) Infrared reflectivity spectra of TIGaS2, TIGaSe2 and TlInS2 layer crystals are measured for the polarization directions perpendicular and parallel to the optical c-axis in the spectral range from 20 to 400 cm-1. The optical dispersion parameters are obtained for both polarization directions. Besides, normal coordinates and effective force constants are determined for high-frequency lattice vibrations.
RECONSTRUCTION OF PERMITTIVITY AND CONDUCTIVITY PROFILES OF A DIELECTRIC SLAB IN THE TIME DOMAIN BY DESCENT METHODS ONDER, M; Kuzuoğlu, Mustafa (Institution of Engineering and Technology (IET), 1992-10-01) An optimisation approach is presented for the problem of reconstructing the permittivity and conductivity profiles of a dielectric slab from the reflected and transmitted field data. The problem is treated as an optimal control problem where the norm of the difference of measured and calculated boundary data is minimised subject to the state equation governing the system. The original constrained optimisation problem is reduced to the evaluation of stationary points of an augmented functional which is obtai...
Numerical and experimental investigation of damping in a dam-break problem with fluid-structure interaction Demir, Abdullah; Dincer, Ali Ersin; Bozkuş, Zafer; Tijsseling, Arris S. (Zhejiang University Press, 2019-04-01) There have been few experimental and numerical studies on damping effects in fluid-structure interaction (FSI) problems. Therefore, a comprehensive experimental study was conducted to investigate such effects. In experiments, a water column in a container was released and hit a rubber plate. It continued its motion until hitting a downstream wall where pressure transducers had been placed. The experiments were repeated using rubber plates with different thickness and material properties. Free-surface profil...
