摘要： A voltage generator may include a plurality of charge pumps, plural sets of delay pipelines and a phase controller. Given M delay pipelines having N stages each, there may be M*N charge pumps each having a triggering input coupled to a respective stage or a respective pipeline. The phase controller may include a plurality of phase control stages interconnecting among the delay pipelines to induce timing offsets among the outputs of the delay stage. In an alternate design, intermediate nodes among the pipeline's delay stages may be coupled to triggering inputs of a sub-set of the charge pumps. The phase controller may have a plurality of phase control stages coupled, respectively, between the intermediate nodes of the delay pipeline and intermediate nodes of the phase control stages may be coupled to triggering inputs of another sub-set of the charge pumps.

摘要： The present invention is a low-ripple power supply comprising a clock generator, a plurality of charge pump modules, and an adder unit. The low-ripple power supply inputs each of a plurality of clock signals generated by the clock generator into each of the plurality of charge pump modules. Since each of the plurality of charge pump modules sends the inputted corresponding clock signal into two paths to be inputted into the first and the second charge pump, respectively, and the corresponding clock signal inputted into the second charge pump undergoes an inversion by the inverter, by adding the first voltage outputted by the first charge pump and the second voltage outputted by the second charge pump, the ripples may be eliminated; finally, the adder unit adds the voltages outputted by each of the plurality of charge pump modules to yield a low-ripple DC voltage.

摘要： Techniques are presented to reduce reversion leakage in charge pump circuits. The exemplary circuit is a charge pump of the voltage doubler type, where the output of each leg is supplied through a corresponding output transistor. An auxiliary charge pump is used to supply the gates of the output transistors in order to cancel the threshold voltage of these output transistors. To reduce reverse leakage back through the output transistors, in each leg of the charge pump a switch is connected between the gate of the output transistor and the output level of the leg so the these levels can be shorted when that particular is not supplying the pump's output.

摘要： A system, method, and computer program product for generating a regulated boosted load voltage. A comparator may use reduced versions of a reference voltage, a supply voltage, and a fed-back output load voltage to determine whether the output load voltage requires adjustment. If so, a controller may responsively vary the number of voltage boosting charge pumps connected in parallel to the load to best match a target voltage. The target voltage may be the reference voltage plus the supply voltage. A counter may track the number of active charge pumps, and may increment or decrement the number more slowly than the charge pumps operate. Loop gain may be limited by an integrating filter to prevent oscillation. The embodiments are of particular utility for signal conversion circuitry as they eliminate difficulties arising from gate-source voltage inadequacies and differences in switch transistors. A wider range of reference voltages may be accommodated.
摘要翻译：一种用于产生调节的升压负载电压的系统，方法和计算机程序产品。比较器可以使用参考电压，电源电压和反馈输出负载电压的减小版本，以确定输出负载电压是否需要调整。如果是这样，控制器可以响应地改变与负载并联连接的升压电荷泵的数量，以最佳地匹配目标电压。目标电压可以是参考电压加电源电压。计数器可以跟踪活动电荷泵的数量，并且可以比电荷泵操作更慢地增加或减少数量。环路增益可能受到积分滤波器的限制，以防止振荡。这些实施例对于信号转换电路特别有效，因为它们消除了栅极 - 源极电压不足和开关晶体管的差异引起的困难。可以适应更宽范围的参考电压。
