Multiple variants of low cost testers have been developed for digital testing which rely on relaxed timing, power or tester channel requirements to lower hardware cost. Systems containing mixed-signal/RF components can thus not be tested on such ATE due to the cost and limitations of analog/RF stimulus and measurement modules. This paper proposes a hybrid BIST scheme for Analog to Digital Converters (ADCs) to enable full production-quality testing with low cost ATE. The two major challenges addressed are generating the input stimulus, and a fully functional at-speed test to maintain the test quality of a pure analog ATE solution.","PeriodicalId":388394,"journal":{"name":"2009 IEEE International Symposium on Circuits and Systems","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126093694","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 particular, since lyrics contain rich information about the semantic structure of a song, our approach incorporates lyrics to overcome the existing difficulties associated with large acoustic variation in music. We further design a constrained clustering algorithm for music segmentation and evaluate its performance on commercial recordings. Experimental results show that our method can effectively detect the boundaries and the types of semantic structure of music segments.","PeriodicalId":388394,"journal":{"name":"2009 IEEE International Symposium on Circuits and Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123256760","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}

Continuous media provide a limited resource for data embedding, which is analogous to the capacity of a wireless communication channel. Here, we characterize the capacity of a host media using the just-noticeable-distortion (JND) of the human visual system (HVS). Furthermore, the collusion attack can be interpreted as a channel shared by multiple users. Based on this analogy, the colluder detection performance can be understood from the viewpoint of throughput. Specifically, we show how to determine instantaneous throughput using the fingerprint-to-interference-plus-noise ratio (FINR), and extend it to the total throughput and the averaged throughput over a time interval. Our analysis provides a good framework to the understanding of collusion attacks and ways to enhance the traitor tracing performance of a fingerprinting system.","PeriodicalId":388394,"journal":{"name":"2009 IEEE International Symposium on Circuits and Systems","volume":"88 3-4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123431437","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}

For low power applications, trace-back approach (TBA) is usually employed for the Survivor Memory Unit (SMU) of VD. However, TBA suffers from long latency and low throughput. Employing multiple memory banks can resolve the throughput issue on a great extent. In this paper, we present efficient schemes to improve the latency issue of conventional TBA by exploiting pre-trace-back method. In the meantime, we adopt buffer-based TBA method to reduce memory access times, thus reduce power assumption significantly. Simulation results show that the proposed decoding schemes cause either zero or negligible performance loss.","PeriodicalId":388394,"journal":{"name":"2009 IEEE International Symposium on Circuits and Systems","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114952603","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 proposed method increases the bandwidth of the pulse up to 10 GHz and overcomes the coexistence problem of UWB and vulnerable narrowband systems through suppressing narrowband interference. Consequently it improves the range of UWB communications by increasing the power, without disturbing the narrowband systems. The pulse technique is implemented in high frequency pulse generation circuits and could be fully integrated in BiCMOS process. The nulls of the frequency response are tuned to be located in a definite narrowband system with the number of the nulls being adjustable too.
