Low Power Vlsi Circuits

International journal of VLSI design & Communication Systems (VLSICS) is a bi monthly open access peer-reviewed journal that publishes articles which contribute new results in all areas of VLSI Design & Communications. The goal of this journal is to bring together researchers and practitioners from academia and industry to focus on advanced VLSI Design & communication concepts and establishing new collaborations in these areas. Authors are solicited to contribute to this journal by submitting articles that illustrate research results, projects, surveying works and industrial experiences that describe significant advances in the VLSI design & Communications.

Sharply increasing need for portable electronic devices has reinforced the need of low power design methodologies in the recent years. Adiabatic logic style is proved to be an attractive solution for low power digital design. The energy is recycled back to power supply instead of being wasted. Many researchers have introduced different adiabatic logic styles in the past few years. This paper discusses the implementation of three quasi-adiabatic logic styles and analyzes the charge flow. All the inverter circuits are designed using 180nm technology in Cadence design environment.

International Journal of Microelectronics Engineering invites high quality manuscripts in the research areas of analog and digital circuit design methodologies. This journal provides a worldwide, regular and comprehensive update on microelectronics engineering. Journal invites significant research and application papers in all the areas listed below. The comprehensive review papers covering recent developments will also be considered

As part of a study of large pT phenomena in photon-proton collisions at the CERN ISR, a search for direct single photon production has been performed. A statistical division of the data sample into the fraction consistent with single photon and the fraction due to multiphoton decays of neutral hadrons is accomplished by measuring the average conversion probability for the sample in a one radiation length thick converter. The fraction of the sample attributable to direct single photon production is 〈γ/all〉 = 0.074 ± 0.012 for 6 GeV/c < pT 10 GeV/c, and 〈γ/all〉 = 0.26 ± 0.04 for pT > 10 GeV/c, with an additional systematic uncertainty of ±0.05 for both values.
