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.
