The use of light-emitting diodes (LEDs) in street lighting applications has been greatly welcomed with the current trends energy saving, environmental protection, carbon reduction, and sustainable development. This paper presents a novel AC-DC LED integrated streetlight driver that combines an interleaved buck converter coupled inductor half-bridge series resonant full-bridge rectifier into sin...

In the design of an active matrix LCD (Liquid Crystal Display), the ratio of the pixel voltage to the video voltage (RPV) of a pixel is an important factor of the performance of the LCD, since the pixel voltage of each pixel determines its transmitted luminance. Thus, of practical importance is the issue of how to maintain the admissible allowance of RPV of each pixel within a prescribed narrow...

reviews in many countries indicate that drivers often talk on mobile (cell) phones. studies have been done on possible effects of concurrent mobile phone use on driving performance. previous studies have found that phone talking could impairs performance on simulated or instrumented driving tasks, using such measures as reaction time, following distance, and situational awareness. most of these...

Gold to Gold Interconnection (GGI) flip chip bonding technology has been developed to bond the driver IC chip on the integrated circuit suspension used in hard disk drives (HDDs). GGI is a lead free process where the Au bumps and Au bond pads are joined together by heat and ultrasonic power under a pressure head.

The development of display scan drivers is an essential step in the effort to develop transparent and flexible display devices based on nanowire transistors. Here we report a transparent nanowire-based shift register that functions as the standard logic circuit of a display scan driver. To form the shift register circuits using only n-type nanowire transistors, a novel circuit structure was int...

With submicron technologies, gate delays are dominated by gate load delays rather than intrinsic gate delays. While the common approach for computing gate load delay (or total gate delay) is through delay tables (or k-factor equations), there are important methodology problems associated with the delay table approach. In this paper, we propose a gate driver model with a Thevenin equivalent circ...

The future trend of controller integrated circuit (IC) for micro hard disk driver (HDD) is to be lighter, thinner, shorter and smaller. The storage capacity and unit cost of micro HDD is lower than of flash memory card. The optimal packaging manufacturing process for driver IC for micro HDD is Chip Scale Package (CSP). However, the production and assemble process for CSP is much more difficult....
