More Information
Summary:Provided is a voltage supply circuit using a charge pump. The voltage supply circuit enhances charge pump output voltage fluctuation characteristics depending on load variation of a charge pump voltage generator (load regulation characteristics) when receiving an operation power supply voltage of the charge pump through a regulator. The voltage supply circuit is configured to feed back fluctuation of a charge pump output voltage to a charge pump voltage regulator. The fluctuation of the charge pump output voltage is compensated through fluctuation of an output voltage of the charge pump to active enhance the load regulation characteristics.
