This paper proposes a planar full ground plane UWB antenna with ability to reject C band (6.3-7.15 GHz) using split ring slots. Unlike most of the planar UWB antennas that use partial ground plane to achieve wide bandwidth operation, the presence of the full ground plane makes the proposed UWB antenna appropriate for wearing applications by decreasing specific absorption rate (SAR) value. In addition, adding the split ring slots to the structure leads to the creation of a notch band and increase the antenna operating band.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"129 1","pages":"1228-1232"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76156213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the large mismatch error in binary-weighted DACs, the use of these in delta-sigma modulators rarely happens. In order to make it possible to use of binary DAC a digital technique is presented. This study aimed to find the error associated with each binary DAC element using the correlation technique between a random signal and a modulator output. Results of simulation on a third-order six-bit delta sigma demonstrated that this method can estimate the error value of each element with high precision and raise the modulator accuracy up to an ideal value, independent of the OSR value. Compared to a six-bit unary DAC calibrated in the same way in which the coefficient of error of 26–1 elements should be calculated, this number was reduced to 6 coefficients in a binary DAC and thus, the time and circuit necessary for calibration significantly decreased.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"15 1","pages":"388-392"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75138019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the suggested comparator, a complementary differential pair is utilized. As a result, the delay time is reduced and the offset voltage is improved. Furthermore, the delay and power consumption has less sensitivity to the variations of the input common mode voltage level. In the reset phase, an NMOS switch is utilized between the differential outputs nodes to reduce the delay time. The equations related to the delay time and input referred offset voltage of the proposed structure are derived and the effective parameters to reduce them are identified. The post-layout simulation results in 65nm CMOS technology demonstrate that the clock frequency of the proposed dynamic comparator can be 6GHz while the delay time is 30ps. The power consumption is 573µW when the proposed comparator is supplied with 1.2V.

This paper deals with modeling the continuous part of a hybrid system by a special Petri net called Continuous Time-Delay Petri Net (CTDPN). According to the theorem presented in this paper, an exact correspondence between discrete- time state space equations and fundamental equations of the CTDPN can be established. Based on this theorem, a systematic method is presented for realization of a continuous system represented by a discrete-time state space model. By integrating the concept of state space models and Petri Nets in this paper, new and effective methods can be proposed for analyzing and modeling of hybrid systems. Finally, the performance of the proposed method is investigated for a DC motor.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"93 1","pages":"1188-1192"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79438076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Albeit the simplicity, the walking gait of passive dynamic walkers resembles human walking in slops very well. The most important drawbacks of these robots is their sensitivity on initial conditions and the limited range of slopes they can have a stable walking cycle on. The aim of this work is to alleviate these problems by adding a link that resembles a torso and controlling it using a Neuroevolutionary algorithm. To achieve this goal, initially the dynamical equations governing this robot was extracted. Then the control algorithm is applied. The reason to use this control strategy is to mimic how natural evolution could play a role in robust biped walking. It was observed that this strategy improved both shortcomings associated with passive dynamic walkers and interestingly the robot shows torso movements familiar to that of humans when facing steep slopes or zero slope.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"24 1","pages":"997-1001"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85064037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, a conformal microstrip antenna with inset feed is considered on dielectric substrate with ε r = 10 grounded by a perfect electric conductor (PEC) cylinder. The working frequency and bandwidth of the patch antenna are 5 GHz and 80 MHz, respectively. Then, a patch frequency selective surface (FSS) is placed on top of the substrate layer except the regions covered by the patch and feed line of the antenna. The FSS, substrate and ground make a mantle cloak decreasing the monostatic and bistatic RCS of the antenna structure from 8.5 GHz to 10.5 GHz. The propagation characteristics of the new antenna are compared with the first one and it is shown that mantle cloaking has negligible effect on impedance bandwidth, gain and pattern of the antenna.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"60 1","pages":"1347-1351"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85653728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multi-layer perceptron (MLP) network has been widely employed to address the problem thanks to its capability in learning the complex nonlinear relationship between the endmembers and their abundances. In this paper, we investigate the application of finding a suitable synthetic library for HSU using MLP. Firstly, fully constrained least square method is utilized to extract the initial solution because of its speed and high accuracy. The synthetic library is only made of samples around the initial solution, which avoids searching in the entire abundance range. Secondly, the discrete cosine transform and discrete wavelet transform are utilized to reduce the number of HS image bands in order to reduce the network's parameters resulting in preventing the overfitting. Since these feature reduction methods are data-independent, they are proper for compacting synthetic libraries. Furthermore, the spectral information divergence is utilized as an objective function in order to achieve a better result. The proposed method is applied to both synthetic and real datasets and the robustness and abundance estimation error has been evaluated. The results illustrate the potency of the proposed method in real applications.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"28 1","pages":"1303-1308"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80907356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
