Circuit for Improving Speed of Switching and Compensating Mismatch of Output Current in Charge Pump Circuit and Control Circuit thereof

摘要

The present invention relates to a correction circuit and a control circuit for controlling the compensation circuit for improving the switching speed of the charge pump circuit and, compensating for the discrepancy between the output current. Compensation circuit according to one embodiment of the present invention is a charge pump circuit a gate of the charge and discharge device of the - by forcing the charge in the parasitic capacitance present on the source and between the source stage inlet or discharge the parasitic capacitance of the performance of the charge pump circuit the impact of the rewards. Control circuit according to one embodiment of the present invention controls the correction circuit such that the correction circuit can be controlled by the amount of charge flowing into and released, the exact compensation made from a parasitic capacitance.
