Up to now the bottleneck for the application of this technique was the possibility of realizing a large number of very-fast read-out channels with reduce power consumption. Typical time separation between each ionization act in a helium-based gas mixture is from a few ns to a few tens of ns. Thus the read-out interface has to be able to process such a high-speed signals. In this paper, the first realization of a CMOS 0.13µm integrated readout circuit, including a fast variable gain amplifier (VGA) with 160MHz bandwidth is designed for the central tracker of a future collider (ILC, super-B). The VGA circuit has been optimized for low power consumption. Moreover, it presents a programmable power consumption (8.4mA, 9.4mA, 10.6mA) according to the gain setting (0dB, 10dB, 20dB). The design issues and the measured performance associated to this architecture are discussed.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123606682","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 system has been conceived for alternate current excited systems, performing simultaneously driving and measuring functions thanks to feedback. The system delivers magnitude and phase signals independently, which can be optimized separately. The method can be applied to any kind of load (resistive and capacitive). Design specifications for CMOS circuit blocks and tradeoffs for accuracy and loop stability have been derived. Simulation results for several loads agree with the theory, enabling its application to any impedance measurement problem, in special, to bio-setups including electrodes.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124656436","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}

Delay variations are also the main issue in subthreshold operation. Consequently, asynchronous logic seems an ideal, and probably unavoidable choice, for the design of digital circuits in nano CMOS or other emerging technologies. This paper examines the robustness of one particular asynchronous logic: quasi-delay insensitive or QDI. We identify the three components of this logic that can be affected by extreme variability: staticizer, isochronic fork, and rings. We show that staticizers can be eliminated, and isochronic forks and rings can be made arbitrarily robust to timing variations.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129631167","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}

Cooperative communications is a promising technique that can overcome this weakness by allowing the users to profit from powerful benefits of the spatial diversity. Nevertheless, abstraction is usually made on the impact of the additional multiple access interference inherent to relaying. In this paper, we propose a novel approach that optimizes the system performance of an amplify-and-forward (AF) relaying scheme subject to a constant multiple access interference cost for the uplink CDMA (Code Division Multiple Access) communications. We present a variety of simulation results illustrating the cellular system performance enhancement in term of BER (Bit Error Rate) over direct transmission.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"279 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126875054","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}
