Abstract

This paper presents a fully integrated DC-DC converter using TSMC 0.18μm & GIPD (tMt Glass Substrate Integrated Passive Device Process) process, which are combined with the 3D IC technology. The sizes of capacitors and inductors are reduced to nano-scale so that they can be integrated into a single chip. The voltage control Pulse Width Modulation (PWM) is used in this paper to obtain a fast transient response. Besides, the converter can be utilized for dynamic voltage scaling (DVS) applications that it can change its output voltage with different voltage requirements from the loading. The voltage conversion is from 1.8V down to 1.3V ~ 0.6V. The maximum voltage conversion efficiency is 78.5% and the maximum load current is 150mA.
