Paper Title
A 10MHz, 2.5 V to 1.2 V two-Stage Power Converter for on-Chip Applications

An efficient, high frequency power management unit (PMU) is reported in this paper. The PMU comprises of a front-end buck converter and a second-stage Low Drop-Out Regulator (LDO). The PMU converts 2.5V from battery power supply to a 1.2V output, with 1A load current capability. The IC is fabricated using 130nm CMOS technology node and occupies an active area of 1.6x1.6mm2. The tested chip has an average end-to-end efficiency of 73 % and is suitable for powering on-chip loads. Keywords - Power management; DC-DC Converter; Buck Converter; LDO
