High area-efficient DC-DC converter using Time-Mode Miller Compensation (TMMC)

Abstract

For the controller design of a DC-DC converter, a Time-Mode Miller Compensation (TMMC) is introduced in this paper. Using this concept, the consuming area of the DC-DC converter can be significantly reduced without any off-chip compensation components. The chip is implemented in 0.18μm I/O CMOS whose size is similar to 0.35μm CMOS, and the core size of this work is only 0.12mm2. Peak efficiency is 90.6%, with switching frequency of 1.15MHz.
