They are often called timers. In low duty cycle systems, such as wireless sensors, such oscillators may incur a significant portion of system power consumption. Extensive research exists in making on-chip oscillators low power. However, the other part of the time keeping function, that of computing the number of oscillation cycles, is normally not treated in such research. This paper describes research that focuses on developing oscillators with an innate capability of counting its own oscillation cycles, suitable for direct use as timekeeping devices. The functional correctness of solutions based on asynchronous counters and matched delays are demonstrated and a number of designs are characterized in terms of oscillation frequency and working ranges. In addition, the proposed timers are seamlessly elastic in relation to voltage variations.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131245776","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}

Generally, these tools handle the circuit sizing and the layout generation processes separately, which may cause performance failures and laborious redesign iterations. Recently, new tools have been developed which simultaneously take care of circuit sizing and layout generation. However, they either suffer from long run times or limited accuracy of the utilized parasitic model. This paper presents a complete layout-aware design automation tool for analog circuits. The proposed tool combines a simulation-based circuit sizing tool with a template-based layout generation tool. The layout-induced parasitics are automatically extracted via a commercially available extractor. To reduce the run time cost originating from parasitic extraction, a two step methodology is followed, where infeasible solutions are prohibited from costly extraction process.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129471389","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}

A numerical and experimental analysis of multimode propagation over co-planar transmission lines, used during the calibration process, is described. The losses and coupling effects arising from the unwanted propagating modes are analysed by means of 3D electro-magnetic simulations. Fused silica is then proposed as an optimal calibration substrate due to its low loss-tangent and low dielectric constant, which allows to reduce, compared to alumina, losses arising from spurious modes. Experimental data of probelevel calibration performed in the 220-325GHz band are presented. A frequency scalable approach to achieve absolute power control for large signal characterization in the (sub)mm-wave bands is introduced. The proposed hardware configuration employs only a commercially available VNA and the required frequency extenders to cover a given band and does not employ expensive additional test-sets. Measurement results are provided in WR-10, WR-05 and WR-03 waveguide bands to report the scalability of the method.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130007295","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 curved surfaces representing the quotient are partitioned into several regions, each of which is then approximated by a square/triangular plane. The planes are obtained by using the curve fitting method for accuracy optimization. The proposed architecture for implementing the planes contains only simple arithmetic operations and a look-up table. Several non-iterative divider circuits with different accuracies and ADPs are obtained. The accuracy achieved in terms of the maximum absolute error percentage (MAEP) ranges from 1.87% to 0.14%. The MAEP of 0.14% is 30% better than the one achieved by the best existing non-iterative divider.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133571176","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}
