摘要： A charge pump comprises one or more pump stages for providing a negative boosted output voltage. Each of the one or more pump stages comprises a P-channel transistor formed in an isolated P-well and an N-channel transistor coupled in series with the P-channel transistor. Forming the P-channel transistor in the isolated P-well essentially eliminates a raised threshold voltage due to body effect.

摘要： A hybrid power converter circuit includes a switched-capacitor power converter stage and a pulse-width modulation (PWM) or resonant output circuit coupled to a switching node of the switched-capacitor power converter stage. In particular, the PWM or resonant output circuit can include a transformer having a primary winding and a secondary winding magnetically coupled to each other, and the secondary winding is coupled to the output node of the power converter. The switched-capacitor power converter stage is coupled between the input node of the power converter and the primary winding of the transformer, and includes capacitors and switches configured to connect the capacitors to the input node during a first phase of operation and connect the capacitors to the primary winding of the transformer of the PWM or resonant output circuit during a second phase of operation.

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。

摘要： Systems, apparatuses, and methods provided for ping-pong charge pumps. Flying capacitors present in ping-pong charge pumps are operated out of phase to increase equalization periods. Out-of-phase operation also decreases voltage differences between flying capacitors during equalization periods thus decreasing ping-pong charge pump output voltage ripple and snapback. The voltages of the flying capacitors may be equalized without the use of an equalization switch. Differential control currents that are based on the voltage difference between the flying capacitors are used to enable or disable the flying capacitors from driving an output load of the ping-pong charge pump during certain phases of operation. A capacitor with a lower voltage may be disabled, thus providing for voltage equalization as the enabled capacitor sources current to the output load. The flying capacitors are also equalized during overlapping time periods in which the flying capacitors are charging.
