Methods proposed in the literature focus mainly on linear decomposition using XOR gates. In this paper we propose an algorithm using discernibility sets. We prove that it minimize standard benchmark functions as efficiently as the best-known algorithms. However, linear transformations seem to be insufficient for some functions. Therefore, we propose a novel approach to the minimization of index generation functions that uses non-linear transformations, i.e. AND gates. We provide examples showing that this technique can further reduce the number of input variables.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"95 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132574424","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 this method, firstly, by the Integer-N synthesizer based on PLL and constructed of blocks of PFD, CP, VCO and Frequency divider the input is increased with integer coefficients and it produces frequencies 2.1GHz, 2.15GHz,..., 2.5GHz very quickly. To get 1MHz steps in the output, a second loop that consists of blocks FVC, VCO and Voltage divider is used. In this method, the input frequency is high compared to the conventional methods, so the first loop will be locked very fast and the second loop will quickly move the output in steps 1MHz. As a result, changing channels will be very quick. This structure is very simple and has a low power consumption and a low output jitter, the proposed structure is designed in 0.18um CMOS process.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114463938","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 order to add two 128-bit numbers, these modified Carry-Look-Ahead Adders are merged with Tree algorithm, that the results of it have a significant improvement in complexity and gates count (25%), compared to the existing methods.

The criterion of correct operation is the level of radiated emission; the value of which depends on the spatial orientation of the cooperating inductors. The sources of the generated harmonic disturbances, which are the nonlinearities of the output stage of the transmitter and the input circuits of the receiver, have been identified. On this basis, a peripheral model was created that allows prediction of the level of disturbances in a given position. The emission measurement in the ALSE chamber in a low frequency band of up to 1.7MHz was used as the verification method. The correctness of the proposed method was confirmed by the evaluation of the interface of the immobilizer commonly used in automotive vehicles.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114178577","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}

This block is part of original sub-ranging ADC whose working principle is based on the assumption that sub-ADC and sub-DAC exhibit high linearity while they nominal resolutions remain relatively low. The linearity of the presented flash ADC has to be as high as in case of 8-bit converter. Thus, the most challenging task was to design comparator with resolution of ±1.5 mV. This goal was reached owing to ability offered by the FD-SOI process to trim transistor’s threshold voltage by means of modulating the back-gate polarization. The resulting sampling rate is 500 Ms/s.","PeriodicalId":309822,"journal":{"name":"2019 MIXDES - 26th International Conference \"Mixed Design of Integrated Circuits and Systems\"","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115222938","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}
