Abstract To meet the high-reliability requirements of switch mode power supply LED driver chips with constant on-time architecture, a detection mechanism circuit that can detect switching frequency architecture is proposed. The completes conversion from to output voltage through separate tracing technology. uses method error calculation eliminate interference jump on detection. design based 180...

The aim of our project is to provide a real time non-intrusive driver drowsiness detection to prevent the rapidly growing accidents caused by sleepy or drunk driver. We are going to merge the 2 requirements for safe driving in a single equipment. The car does not function unless the two conditions of safe driving are satisfied. Bio signals, such as brain waves, pulsation waves, and heart beat a...

A novel image contrast enhancement (ICE) circuit was proposed by modulating the reference voltages of the source driver circuit in liquid-crystal displays (LCDs). The adjustment of reference voltages is achieved immediately by applying external adjustment codes, which may be generated in accordance with the video data distribution on image displays and the liquid crystal materials, and leads to...

It has been shown [2] that adiabatic switching can significantly reduce the dynamic power dissipation in an integrated circuit. Due to the overhead in the realization of adiabatic logic blocks [3] the best results are achieved when it is used only for charging dominant loads in an integrated circuit [7]. It has been demonstrated [4] that a multi stage driver is needed for minimal power dissipat...

The width of an interconnect line a ects the total power consumed by a circuit A tradeo exists however between the dynamic power and the short circuit power in determin ing the width of inductive interconnect The optimum line width that minimizes the total transient power dissipation is determined in this paper A closed form solution for the op timum width with an error of less than is presente...

It has been shown (Athas et al., 1994) that adiabatic switching can significantly reduce the dynamic power dissipation in an integrated circuit. Due to the overhead in the realization of adiabatic logic blocks (Saas et al., 2000) the best results are achieved when it is used only for charging dominant loads in an integrated circuit (Voss and Glessner, 2001). It has been demonstrated (Saas et al...
