Comparative characteristics of thick-film integrated LC filters

IEEE Transactions on Instrumentation and Measurement (2002)

Vladan Desnica Lj. Živanov O.S. Aleksić Miloljub D. Luković M.D. Nimrihter

The paper describes the design, fabrication, and test of integrated LC filters in thick-film technology. The range of filters was electrically characterized using the HP 8566B network analyzer. We present a scalable analytical model for thick-film integrated LC filters that is suitable for design and circuit simulations. We also provide simple expressions for evaluating the optimum conductor thicknesses.

EM Simulator Analysis of Optimal Performance Thick-Film Segmented Thermistors versus Material Characteristics Selection

IEEE Transactions on Instrumentation and Measurement (2008)

Viktor Maric Miloljub D. Luković Lj. Živanov O.S. Aleksić Aleksandar Menicanin

In this paper, an alternative approach to the analysis of thick-film segmented negative temperature coefficient thermistors based on the use of a commercial electromagnetic simulator tool is presented. The influence of the geometrical parameters and material characteristics of the used thermistor paste on the overall thermistor performance was analyzed and simulated. A physical model for the segmented thermistors is given in brief, together with experimental data. The diffusion of electrode metal into the thermistor layer was analyzed, simulated, and estimated. Obtained simulation results were compared with experimental results, and the validity of the adopted approach was verified.

The influence of higher minima on physical parameters in ultra heavily doped n-type GaAs

Miloš B. Živanov Lj. Živanov Jovica Jovović

In this paper was calculated the position of Fermi energy level and effective mass of electron in n-type GaAs as a function of donor concentrations in the range from 10/sup 17/ to 10/sup 21/ cm/sup -3/, taking into account upper minima in conduction band at 300 K. Calculations show that is necessary taken besides /spl Gamma/ and L minimum for concentrations greater than 10/sup 19/ cm/sup -3/ and all three minima (/spl Gamma/, L and X) for concentrations greater than 10/sup 20/ cm/sup -3/.

A characterization of ceramic SMD inductors for PCB applications

Aleksandar Menicanin Mirjana Damnjanović Lj. Živanov

In this paper, a measurement technique, characterization and parameters extraction of SMD inductors for PCB applications are presented. These components, manufactured by Fair-Rite, are measured and characterized using a vector network analyzer E5071B and adaptation test fixture on PCB board. Since the behavior of the component depends on the environment where the component is placed, measurement results strongly depend on the choice of the PCB. Two new adaptation test fixtures in PCB technology on different board type are presented. The equivalent circuit parameters are extracted in closed form, from an accurate measurement of the board-mounted SMD inductor S-parameters. The extraction of parameters (intrinsic and extrinsic) of SMD inductor is shown.

Characterization of Printed Humidity Sensor Based on Nanoparticle Copper Oxide

Čedo Žlebič Lj. Živanov Nelu Blaž Milica Kisić Miloljub D. Luković

In this paper, flexible and low cost humidity sensor based on nanoparticle CuO is presented. The sensing layer, dimensions of 21 × 17 mm ² , is printed using the 3D printer (nano3D print A2200). It is deposited over 22 fingers of the interdigitated capacitor. The electrodes of the interdigitated capacitor were printed with nanosilver ink. The width and the spacing between the fingers were 200 pm and 600 pm, respectively. The electrodes of the interdigitated capacitor are deposited on the PET substrate. The capacitance of the fabricated sensor with humidity change in the range from 30 % to 90 % at two temperatures (40 and 60 °C) was measured at a frequency of 100 Hz. Also, the hysteresis and the response/recovery behaviour and repeatability characteristics were evaluated. The response/recovery times were 36 s and 51 s. It is obtained satisfactory repeatability.

Analysis of effects of material and geometrical characteristics on the performance of SMD common mode choke

Mirjana Damnjanović Lj. Živanov Goran Stojanović

In this paper, proposed structures of ferrite common mode chokes for suppression of conductive electromagnetic interference (EMI) will be presented. These surface-mount devices are widely used in modern electronic equipment for suppression or reduction of EMI. Choke consists of two multilayer spiral type inductors, embedded in ferrite monolithic structure. To obtain the optimal design of choke, the simulation tool ILCMC for calculation of insertion loss of common mode choke is developed. Using ILCMC we have simulate the effects of material and geometrical characteristics on the common mode choke performance. Insertion losses of proposed components are calculated and compared. Goal of this paper is to explore the optimal design of EMI chokes. These simulation results will be very useful for construction of the ferrite common mode chokes.

A Novel Approach to Extending the Linearity Range of Displacement Inductive Sensor

IEEE Transactions on Magnetics (2008)

Mirjana Damnjanović Lj. Živanov L. Nagy Snezana Djuric B.N. Biberdzic

This paper presents a meander-type displacement inductive sensor, usable for the detection of small displacements (less than 0.5 mm) in the plane. It also describes design, realization, and the input inductance measurement of sensor. A displacement in two directions can be detected by using two sensor elements, each having a pair of meander coils. In each pair, one of the coils is fixed and between its terminals the input inductance was measured, while the other coil is short-circuited. If one coil is moved above the other, in directions of x - and z -axes, coupling between the coils will change, as well as the input inductance, which serves as a measure of displacement. In order to achieve better linearity of the sensor, longitudinal gaps are inserted in the middle of each conductive segment of one fixed coil. Four sets of inductive sensors were realized: without gap and with three different gaps. Planar, low-cost PCB technology was chosen for our prototype. In addition, an improved model of the inductive sensor is proposed. The input inductance of displacement sensor was calculated and compared with measured values. A good agreement was found.

Dielectric properties of strontium hexaferrite in microwave, infrared and far infrared ranges

P.M. Nikolić Lj. Živanov O.S. Aleksić

Presents the dielectric properties of polycrystalline SrF/sub 12/O/sub 19/ in the microwave range and far infrared range. Samples were made from powder pressed in a magnetic field and sintered in air at 1200 degrees C. The experimental results and numerically calculated dielectric permittivity in the far infrared range show that the dielectric permittivity holds a microwave value and in mm-wave range. The transmission characteristics of a thick film Sr- hexaferrite isolator in fin line technique were observed in the range 32.7-39.2 GHz. The bandwidth over which the isolation loss is greater than 20 dB is about 2 GHz (at around 36 GHz). Ferrite devices in this geometry have the advantage of being compact and of low cost compared to the ferrite devices in conventional structures. >
