Abstract

A single-inductor-cascaded-stage boost regulator topology is presented that time-multiplexes a single inductor using one-nFET-two-pFET power stage and a bias-gated Pulse-Frequency Modulation controller to achieve high conversion ratio. A test-chip in 130nm CMOS demonstrates 120× conversion using a single inductor while consuming 140nA bias current.
用于高转换率升压稳压器的单电感级联级拓扑结构
提出了一种单电感级联升压调节器拓扑结构,该拓扑结构利用一个nfet -两个pfet功率级和一个偏置门控脉冲调频控制器对单个电感进行时间复用,以实现高转换率。130nm CMOS测试芯片在消耗140nA偏置电流的情况下,使用单个电感实现了120x转换。
