The Conference Proceedings contains papers presented at the 2013 36th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO) held from May 20th to 24th 2013 at the Grand Hotel Adriatic Convention Centre in Opatija, organized by MIPRO Croatian Society and technically co-sponsored by IEEE Region 8. Papers are from the following fields: Microelectronics,...
Presents the table of contents of the 2013 36th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO) proceedings record.
In numerous practical circuit applications, including waveshaping and nonlinear function generation, waveforms are intentionally clipped. That can be achieved in many different ways using diodes, transistors and integrated circuits. In this paper (invited lesson), we are going to show how dedicated min and max circuits can be used for mentioned purpose(s). Also, we are going to show how dedicated...
The electronic properties of molybdenum disulfide have been modified by substitution of molybdenum atoms with non-isovalent Re and Nb atoms. Similar approach results in preparation of semiconducting Mo1−xRexS2 and semimetallic Mo1−xNbxS2 materials. These solid solutions were exfoliated in organic solvents. Nano size colloidal dispersions were used for preparation of thin films. All materials are characterized...
Porous silicon (PSi) samples were prepared by electrochemical anodisation of silicon on insulator layers. Structural and optical properties of prepared samples were investigated by Raman and photoluminescence (PL) spectroscopy and field emission scanning electron microscopy (FE-SEM). The anodisation of silicon on insulator layers was performed by alternating currents (AC) of the mains frequency of...
Macro and meso-porous silicon (PSi) samples were prepared by electrochemical anodisation of p− and p++ doped silicon wafers in hydrofluoric acid (HF) based electrolyte under galvanostatic conditions. Anodisation time and current were varied in order to obtain different PSi morphologies. Samples were characterized by scanning electron microscopy (SEM), photoluminescence (PL) spectroscopy and Raman...
We discuss problems in the preparation and analysis of the solid solution phase in the case of heavily phosphorus and boron doped polycrystalline silicon. Some currently used methods and the technology of polysilicon thin films preparation are presented. Based on and afore these discussions, we propose a process of preparation of a good quality heavily boron and phosphorus doped silicon thin film...
Ge2S3-based films have been investigated using Raman, photoluminescence and photoemission spectroscopy. For the sake of comparison some of the photoluminescent properties of bulk glasses have been used. The synchrotron photoelectron spectroscopy (SRPES) and XPS spectra of a-Ge2S3 films have been measured after the illumination and annealing. The changes in the parameters of the film's core levels...
Spherical microresonators were coated using a 70SiO2 - 30HfO2 glass doped with 0.3 mol% Er3+. The sphere was characterized by coupling a 1480 nm pump laser inside the sphere using a tapered optical fiber and observing the 1530–1580 nm Er3+ emission outcoupled with the same tapered fiber. The measurements were done for different coating thicknesses and compared with theoretical calculations to understand...
The paper presents structural and luminescence studies of two lanthanide phosphate composites codoped with different concentrations of Eu3+ and Yb3+ ions. The powders of polycrystalline phosphates were synthesized by the modified Pechini method. The composition and morphology of the samples were characterized using inductively coupled plasma atomic emission spectrometry and transmission electron microscope...
As transistors are scaled down to nanometers, the theory and structure of nanometers devices such as carbon nanotubes field effect transistors (CNTFET) are being extensively studied. Self consistent solution of the Poisson and Schrödinger equations is performed using the non-equilibrium Green's function (NEGF) formalism to investigate the impact of nanotube diameter, gate oxide thickness and high-k...
Many applications, particularly in the medical and bio-medical fields, require highly sensitive detectors in the short wavelength range (blue and below); so far there have been few commercially available avalanche photodetectors with adequate performance to satisfy demands of such applications. We have developed a new silicon reach-through avalanche photodiode (RAPD) operating in the blue wavelength...
Hundred and seventy-five thousand device-hours of operating life at channel temperatures above 200°C is demonstrated on AlGaN/GaN HEMTs fabricated using GaN-on-diamond technology for the first time. No catastrophic failures and no drain-current drift larger than 10% from turning the devices on were recorded throughout this two-year DC test.
Emerging new applications, such as wireless sensor nodes powered by energy harvesters, demand the change of the circuit design paradigm. Namely, for the past years, designers aimed at the minimum delay point in the energy-delay space, while the aforementioned applications require that the minimum energy point becomes the priority. One of the ways to achieve low energy consumption, while neglecting...
Compressors are the most important component of multipliers. Multipliers themselves are important components that dictate the overall performance of arithmetic circuits. In this paper, a new 4–2 compressor architecture is proposed. This architecture uses Carry Generator Module (CGEN) which has been used for 5–2 and 7–2 compressors already. The proposed architecture is compared with the best architecture...
In this paper a method of realizing seventh-order elliptic filter using signal-flow graphs is presented. The elliptic filter having a minimum number of capacitors is compared with the filter having a higher number of capacitors. The version with minimum number of capacitors provides area savings in IC form. Both filters (i.e. filter with minimum and one with higher number of capacitors) have a low...
