CMOS LNA design for LEO space S-Band applications

Telli, A
Askar, M
In this study, LNAs for low earth orbit (LEO) S-Band uplink/downlink "System-on-Chip" receiver stages with different topologies are designed and simulated using the Mietec CMOS 0.7mum process and the Cadence/BSIM3v3 tool.


CMOS planar spiral inductor modeling and low noise amplifier design
Telli, A; Demir, S; Askar, M (Elsevier BV, 2006-01-01)
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 i...
Cmos LNA design for system-on-chip receiver stages
Telli, A; Askar, M (2004-09-10)
In this study, narrowband single-ended inductive source degenerated Low Noise Amplifiers (LNAs) for "System-on-Chip" receiver stages have been designed, simulated and compared using Mietec CMOS 0.7 mu m process and the Cadence/BSIM3v3 tool with active or L-biased DC-bias circuitries. Since there is an intension to use LNAs for GSM and S-band low earth orbit (LEO) space applications, the operating frequencies have been chosen as 900MHz, 2025 MHz and 2210 MHz.
Opti-acoustic stereo imaging
Saç, Hakan; Leblebicioğlu, Mehmet Kemal; Salor Durna, Özgül; Department of Electrical and Electronics Engineering (2012)
In this thesis, opti-acoustic stereo imaging, which is the deployment of two-dimensional (2D) high frequency imaging sonar with the electro-optical camera in calibrated stereo configuration, is studied. Optical cameras give detailed images in clear waters. However, in dark or turbid waters, information coming from electro-optical sensor is insufficient for accurate scene perception. Imaging sonars, also known as acoustic cameras, can provide enhanced target details under these scenarios. To illustrate these...
Orbital and spin phase-resolved spectroscopy of the intermediate polar EX Hya using XMM-Newton data
Pekon, Y.; Balman, Şölen (Oxford University Press (OUP), 2011-02-01)
We present the orbital phase-resolved spectra of an intermediate polar, EX Hya, together with the spin phase-resolved spectra during two different epochs using the X-ray Multi-Mirror Mission (XMM-Newton), European Photon Imaging Camera (pn instrument). We find that the source at the two epochs has the same X-ray luminosity of similar to 6.5 x 1031 erg s-1. We detect spectral variations between the 2000 and 2003 observations of the source. We fitted the spectrum using a neutral hydrogen absorption model with...
Numerical analysis of radio frequency inductively coupled ion thruster and computation of its performance parameters
Bozkurt, Erdal; Alemdaroğlu, Nafiz.; Department of Aerospace Engineering (2019)
The main goal of this thesis is geometric and parametric analysis of a simulated cylin-drical two-gridded Radio Frequency Inductively Coupled (RF-ICP) ion thruster. Inaddition, instrumental performance of this thruster and the effects of a fixed shapeof the electrodes on ion trajectories are investigated. The simulations of the plasmaand the ion optics are performed by using COMSOL Multiphysics software. The firststep is checking the reliability of the software. Radial and axial simulation parametricresults...
