Possibility of applying memristors in microwave filters [PDF]

open access: yesTehnika, 2016
This paper discusses the possibility of applying memristors in microwave passive circuits such as filters. Basic information about memristor like theoretical assumptions, realisation, structure, and physical properties of the component are presented.

Absolute calibration of the spectral responsivity of thermal detectors in the near-infrared (NIR) and mid-infrared (MIR) regions by using blackbody radiation [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2021
The Physikalisch-Technische Bundesanstalt (PTB) has set up an additional measurement approach for the absolute calibration of the spectral responsivity of detectors in the near-infrared (NIR) and mid-infrared (MIR) spectral range. This alternative method

Can a second order bandpass sigma delta modulator achieve high signal-to-noise ratio for lowpass inputs [PDF]

open access: yes, 2008
Institutively, second order SDMs usually achieve lower SNR than high order ones because high order loop filters can achieve better noise shaping characteristics. Moreover, the signal transfer function should be designed to have large values and the noise

Global stability, limit cycles and chaotic behaviors of second order interpolative sigma delta modulators [PDF]

open access: yes, 2011
It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively.

Determination of the embedded thermo-optical expansion coefficients of PbTe and ZnSe thin film infrared multilayers [PDF]

open access: yes, 2015
This paper reports the first derived thermo-optical properties for vacuum deposited infrared thin films embedded in multilayers. These properties were extracted from the temperature-dependence of manufactured narrow bandpass filters across the 4-17 µm ...

New Compact Microstrip Filters Based on Quasi Fractal Resonator

open access: yesAdvanced Electromagnetics, 2018
This paper presents new microstrip devices  as single band bandpass and multi band bandstop filters. The proposed filters use  slotted patch microstrip resonator based on quasi fractal geometry, simulated by AWR12 software package.
