A Simo Dc-Dc Boost Converter With High Efficiency And Small Area

In this paper, a small area and a high efficiency Single Inductor Multiple Output (SIMO) Boost converter with Digital Pulse Width Modulation (DPWM) using Interlaced Hysteresis Delay Cells (IHDCs) is proposed. This technique has advantage of small area and high efficiency from prior works. The DPWM is composed of Delay Line using Interlaced Hysteresis Delay Cells. The fabrication CMOS Process is 55nm with a standard supply voltage of 1.8V and having 2.2V and 2.4V at its output. The area occupied by the chip is about 170 mu m x 190 mu m and efficiency is 94.00%.
