This paper proposes a new semi-analytic modelling of galaxy properties in the IR/submm wavelength range, which is explicitly set in a cosmological framework. This type of approach has had some success in reproducing the optical properties of galaxies. We hereafter propose a simple extension to the IR/submm range. We estimate the IR/submm luminosities of ``luminous UV/IR galaxies'', and we explore how much star formation could be hidden in heavily--extinguished, ``ultraluminous IR galaxies'' by designing a family of evolutionary scenarios which are consistent with the current status of the ``cosmic constraints'', as well as with the IRAS luminosity function and faint counts, but with different high-z IR luminosity densities. However, these scenarios generate a Cosmic Infrared Background whose spectrum falls within the range of the isotropic IR component detected by Puget et al. (1996) and revisited by Guiderdoni et al. (1997). We give predictions for the faint galaxy counts and redshift distributions at IR and submm wavelengths. The submm range is very sensitive to the details of the evolutionary scenarios. As a result, the on-going and forthcoming observations with ISO and SCUBA (and later with SIRTF, SOFIA, FIRST and PLANCK) will put strong constraints on the evolution of galaxies at z=1 and beyond.Comment: 21 pages, Latex, 20 postscript figures, accepted for publication in Month.

Time-correlated single-photon counting (TCSPC) is a powerful technique for time-resolved measurement of fast and weak light signals used in a variety of scientific fields, including biology, medicine, and quantum cryptography. Unfortunately, given its repetitive nature, TCSPC is recognized as a relatively slow technique. In the last ten years, attempts have been made to speed it up by developing multichannel integrated architectures. Yet, for the solutions proposed thus far, the measurement speed has not increased proportionally to the number of channels, reducing the benefits of a multichannel approach. Recent theoretical studies and prototypes have shown that it is possible to implement a new multichannel architecture, so-called router-based architecture, capable of optimizing the efficiency of data transfer from the integrated chip to the data processor, increasing the overall measurement speed. However, the first implementations failed to achieve the theoretical results due to implementation flaws. In this paper, we present a new logic for the router-based architecture that can operate at the same laser frequency and solve the issues of the previous implementation. Alongside the new logic, we present a new integrated low-jitter delay line combined with a new method for timing-signal distribution that allows the proper management of the pixel timing information. The new implementation is a step closer to realizing a router-based architecture that achieves the expected theoretical results. Simulations and bench tests support the results here reported.

Vector Controlled Delay Cell with Nearly Identical Rise/Fall Time for Processor Clock Application

In the design of modern processor chips, proper clock distribution is a very important aspect which impacts the chip performance. It is the active cell of delay circuits and cells with variable delay that have the major involvement in clock distribution, thereby deciding the time slacks of all functionalities inside the chip. Because they help in proper input to output signal transmission with the adjustment of variable timing delays and monitor the output signal to have equal rise/fall time, which most of the existing delay elements fail to deliver. Therefore in this article, we have proposed an input vector based design of variable delay with balanced rise time and fall time for the output signal. We have also estimated the delay and output voltage in terms of a mathematical model. This new configuration is executed across the commercial platform of Cadence Virtuoso® using 90nm technology node while steered by a 1GHz input signal and power supply of 1.1 V. The execution outcome confirms the desired features of our proposed design under typical conditions and even in process corner variations.
