Abstract

An on-chip low power single-inductor dual-output DC-DC converter is proposed for battery and solar cell operating sensor network applications. By a new feed-forward control, a test chip fabricated by 190nm CMOS achieves a high efficiency of 87% at the practical load condition with a small area size of 0.75mm2 without any compensation capacitor. In addition, the fluctuation of the output voltage remains within 100mV when the input voltage changes from 1V to 2V. For a solar cell operation, 0.5V start-up is achieved with a process technology of flash-memory embedded micro-computers by utilizing forward back bias. A super capacitor is charged up to 5V from a solar cell with an implemented MPPT.

一种0.5V启动87%效率0.75mm2片上前馈单电感双输出(SIDO)升压DC-DC变换器，用于电池和太阳能电池运行传感器网络微型计算机集成

提出了一种用于电池和太阳能电池操作传感器网络的片上低功耗单电感双输出DC-DC变换器。通过一种新的前馈控制，在实际负载条件下，用190nm CMOS制作的测试芯片在没有任何补偿电容的情况下，面积只有0.75mm2，效率高达87%。另外，当输入电压从1V变为2V时，输出电压的波动保持在100mV以内。对于太阳能电池的工作，0.5V的启动是利用闪存嵌入式微型计算机的工艺技术，利用前后偏置。超级电容器由太阳能电池充电至5V，实现了MPPT。
