Abstract:
1. A system for regulating voltage levels, the system comprising: a voltage source being configured to provide a first reference voltage; a first voltage adjustment module being configured to receive an input voltage, the voltage adjust module being adapted to output a calibration voltage; a second voltage adjustment module being configured to output a second reference voltage, the second reference voltage being proportional to the calibration voltage at a predetermined ratio; a voltage comparison module being configured to receive the second reference voltage and the calibration voltage, the voltage comparison module being configured to output a first signal based on a voltage difference between the second reference voltage and the calibration voltage; a clock module being configured to provide a clock signal; a control module being configured to receive the first signal and the clock signal, the control module including a logic unit for generating a second signal based at least on the first signal and the clock signal; and a third voltage adjustment module being configured to receive at least the second signal, the third voltage adjustment module including one or more transistors, the third voltage adjustment modeling being configured minimize the voltage difference using the second signal, the third voltage adjustment further being configured to generate a third signal, the third signal being used for regulating voltage levels.
