In this work, a high precision current source circuit by means of switched-capacitor and PLL(phase-locked loop) for BOST(build-out-self-test) is presented. A relationship between the reference current value and switching-frequency is analyzed to improve the precision of current source circuit. The proposed circuit operates under 3.3V supply with a 100pA reference current source according to Hspice simulation and shows a precision less than 0.8%.

Both changes in speed and protocols in data transfer via satellite links will be an attraction for various services and will extend the terrestrial network to remote areas without the need for costly and limited terrestrial network. However, high frequency satellite links are subject to climatic impairments, especially rainfall. In varying weather conditions, these links show wide variations of bit errors and could not allow the achievement of reliable communication. In some existing systems, these problems are solved by providing the system an extra power margin. At these frequencies and above, the link margin is about 10-20dB. If this supply power is provided for a long period of time, the considered system will turn to be inefficient. It seems therefore important to conduct some experiments in order to develop new protocol or improve existing one for an efficient and reliable data transfer. The non-permanent access to satellite links for experimental purposes can be supplied by indoor apparatus or computer software that generates test conditions approximating actual or operation conditions. Up to now, some satellite link simulators are being developed [1]. These simulators use an Additive White Gaussian Noise (AWGN) to generate the channel error which is not generally the case for satellite links under climatic effects. The intent of this paper is to present and evaluate an efficient bit error generation algorithm based on the statistical analysis of the received signal level in practice. This algorithm is one of the key points for developing a satellite link simulator suitable for the design of today and future communication links[2].

Orientation dependent solid-phase growth of /3-FeSi2 thin films on (100), (110), and (111) Si substrates has been investigated by using a-Fe(thickness: 20 nm)/c-Si stacked structures. XRD measurements suggested that the substrate orientation dependence of the formation rate of /3-FeSi2 was as follows: (100) > (111) > (110). This dependence can be explained on the basis of the lattice mismatch between /3-FeSi2 and Si substrates, i.e., the lattice mismatch between 13-FeSi2 (100) and Si (100), / -FeSi2 (110) or (101) and Si (111), and 13-FeSi2 (010) or (001) and Si (110) are 1.4-2.0%, 5.3-5.5%, and 9.2%, respectively. The substrate orientation dependence of solid-phase growth becomes relatively remarkable for very thin films.

Separation of DNA fragments is performed in on-chip electrophoresis microcapillary fabricated on a photosensitive glass. Since the UV-irradiated part of the photosensitive glass has the etching rate 20 times higher than the other parts, we can obtain the channel structure with the high aspect ratio, which is valuable to the high-sensitivity detection of the signal. The confocal laser scanning microscopy (CLSM) is used to observe and detect the fluorescent sample plug in the on-chip electrophoresis microcapillary. The CLSM is a powerful tool to observe and detect the sample inside the channel since it can capture the fluorescence images and can vary the laser focal plane depth. In this study, Hydroethylcellurose (HEC) polymer solution is using in the electrophoresis as sieving matrix. Therefore the on-chip electrophoresis microcapillary with the short separation channel is able to separate DNA fragments.
