Dynamic voltage generation device and the usage method thereof

Abstract

The present invention provides a dynamic voltage generation device and the usage method thereof, which is used to output the dynamic voltage and adjust the sampling resistance of the sampling switch. The device comprises a reference switch, ensuring that if the reference switch is matched with the sampling switch, the reference resistance of the reference switch is equal to the sampling resistance. The reference switch obtains the reference resistance based on a fixed voltage and a reference current, wherein the ratio of fixed voltage to reference current is the target resistance. The feedback circuit is coupled with the reference switch to output the dynamic voltage to the reference switch and the sampling switch, and adjusting the dynamic voltage based on the fixed voltage and the reference current, so that the reference resistance is equal to the target resistance.
