Abstract
- This paper presents a voltage regulator topology, implemented using low-voltage devices, for converting high input voltage (>4.5 V) to low output voltages with fine-grain control (0.3 to 1 V). The topology merges a Dickson's switched-capacitor stage with a current-mode inductive buck stage, and optimizes the frequency of operations to reduce the overall passive size. The proposed two-stage hybrid regulator, designed in 130-nm standard digital process, operates from 4.8 to 6 V at input and regulates output voltage as low as 0.3 V with a maximum output power of 90 mW and a peak efficiency of 69%.
