Fully On-Chip Low-Drop Regulator for Low-Power Applications

The paper is focused on the design and analysis of a fully on-chip Low-Drop Regulator (LDO) that was implemented in 130 nm CMOS technology. The proposed LDO was designed using the low-voltage technique in order to achieve reliable work in the wide input voltage range. The output voltage of the proposed LDO was set to 0.4 V while the maximum input voltage value of 1.2 V was used. The achieved results shows very good line and load regulation as well as high voltage conversion efficiency under the above-mentioned supply voltage conditions. The presented LDO has been used in a complex ultra-low voltage system that is fully integrated on a chip.
