A Scalable Hybrid Regulator for Down Conversion of High Input Voltage Using Low Voltage Devices
This paper demonstrates a voltage regulator topology, implemented using low voltage devices, for converting high input voltage (>4V) to low output voltages with fine-grain control (0.3V to 1V) for powering digital devices in deep-submicron node. The topology merges a Dickson's switched capacitor (SC) stage with a current mode inductive buck (IB) stage, and optimizes frequency of operations to reduce the overall passive size. The proposed two-stage hybrid regulator, designed in 130nm standard digital process operates from 4.8V-6V at input and regulates output voltage as low as 0.3V with a maximum output power of 90mW and a peak efficiency of 69%.
