With the sinusoidal charging scheme, the large dc link capacitance of the on-board battery charger can be reduced significantly. However, the variable charging current together with the wide battery voltage range imposes serious challenge to maintain high efficiency throughout the whole charging procedure. This paper proposes a LLC dc-dc transformer (DCX) battery charger solution to improve the efficiency...
Recent publications have shown that clock jitter can improve timing margin through the compensation effect between the clock cycle and the datapath delay under the influence of resonant supply noise. In this paper, novel phase-shifted clock buffer designs are proposed to enhance this ldquobeneficial jitter effectrdquo. Compared with existing designs, our design saves 85% of the clock buffer area while...
A fact that has generally been unnoticed is that sleep transistors for leakage reduction can significantly damp the resonant supply noise due to their series resistance. This paper describes an optimal sleep transistor sizing method considering the dominant resonant supply noise. We show that a smaller sleep transistor can offer a smaller worst case supply noise due to the increased damping. We also...
