Time-to-digital converter(TDC) is usually used in measurement of distance. Due to the best choose of measuring is infrared rays. And the speed of infrared rays is very fast. So the resolution of TDC is researched in many persons. It consumed a lot of chip size and higher power consumption in traditional design.Although the TDC by CMOS processing had high resolution just now, the range of measurement is very narrow. So the way to design a high resolution TDC with wide measuring range is very important.

Several implementations of the flyback topology and half-bridge (HB) topology were considered. Specifically, the constant frequency PWM flyback converter, the variable frequency (VF) flyback converter, the VF flyback converter with a synchronous rectifie r (SR), asymmetrical HB converter, and resonant HB converter were evaluated. The comparative evaluation was performed with respect to the conversion efficiency, component stress, output-filter size, and complexity.

In this paper,we studied the effects of phase angle and transmission to the wafer process window of a 193nm EAPSM in a 300mm wafer manufacturing environment. We first fabricated a special multi phase EAPSM by a combination of extra Quartz etch and Mo si removal. We then used a high NA 193nm scanner and high contrast resist to perform the wafer level printing study. To fully understand the impact of phase-angle and transmission to wafer process windows.

The LED could be considered the ultimate general source of continuous light due to its high luminescence efficiency, quickly response and long lifetime. The only significant problem which previous prevented the widespread application of colored LEDs has b een the lack of high intensity LED. As blue is one of the three primary colors blue is required to reproduce the full color spectrum and pure white light. So, the development of mass production technology of LED is an important milestone of application.

A conventional color histogram (CCH) considers neither the color similarity across different bins nor the color dissimilarity in the same bin. Therefore, it is sensitive to noisy interference such as illumination changes and quantization errors. This pape r presents a new color histogram representation, called fuzzy color histogram (FCH), by considering the color similarity of each pixel’s color associated to all the histogram bins through fuzzy-set membership function.
