Abstract

In this paper a fully integrated DC/DC converter for Thermal Energy Harvesting is presented, it is based on a parallel stages architecture as a technique to increase the conversion efficiency without using frequency or duty cycle modulation. The circuit was designed for a CMOS 180 nm process, with an active area of \(954\,\upmu {\mathrm{m}} \times 341\,\upmu {\mathrm{m}}\). The post-layout simulation shows a 87\(\%\) peak efficiency with 1.2 V for a minimum operating input voltage of 250 mV at 33 kHz of switching frequency.

完全集成的并联级转换器，用于热能收集

摘要

本文提出了一种用于热能收集的完全集成的DC / DC转换器，它基于并行级架构，是一种无需使用频率或占空比调制即可提高转换效率的技术。该电路设计用于CMOS 180 nm工艺，其有效面积为\（954 \，\ upmu {\ mathrm {m}} \ times 341 \，\ upmu {\ mathrm {m}} \\）。布局后仿真显示，在33 kHz的开关频率下，最小工作输入电压为250 mV时，1.2 V的峰值效率为87 \（\％\）。
