The filter is composed of two tri-section stepped impedance resonators cascaded and two end-open L-shaped microstrip lines for the input and output feed lines. The harmonic suppression of the bandpass filter may be realized by choosing proper lengths for the L-shaped microstrip lines and proper impedance ratios of the stepped impedance resonator. The filter has been investigated numerically. Simulation results show that the second-order harmonic response is effectively suppressed, and the rejection level is kept below -19 dB.","PeriodicalId":120984,"journal":{"name":"2007 7th International Conference on ASIC","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129903486","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}

Interconnection networks of regular topologies can be designed as IP cores to reduce the well known design-productivity gap. Therefore, regular topologies are more preferred than irregular topologies. To solve the scalability problem of the NoC designs with homogeneous regular topologies, we propose a new NoC design methodology that uses heterogeneous regular topologies. We illustrate the proposed heterogeneous design methodology with a simple configurable regular interconnect topology set, which consists of three subtopologies with different network performances and silicon overheads. Evaluation of the three subtopologies reveals that subtopologies with more connections result in better network performance and more wire complexity. The contribution of the proposed heterogeneous design methodology is that it provides a flexible way to scale the interconnection networks of regular topologies according to the traffic requirements.","PeriodicalId":120984,"journal":{"name":"2007 7th International Conference on ASIC","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127179410","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}

With the conventional first-order compensation, the temperature coefficient is 14.6 ppm/degC over the range from -40degC to 85degC. Due to curvature compensation, an improved temperature drift of 7.04 ppm/degC is obtained.
