Voltage Regulator and a Method for Reducing an Influence of a Threshold Voltage Variation |
摘要 |
A voltage regulator can provide a regulated output voltage. The voltage regulator includes a regulating module that includes a resistor and a field effect transistor that has a threshold voltage. The resistor is coupled to a gate terminal and a source terminal of the field effect transistor. The regulating module provides the output voltage. A reference module is suitable for detecting a variation of the output voltage. The reference module is coupled with the regulating module. A current sink is suitable for subtracting a compensation current from the current flowing from the regulating module to the reference module. The compensation current is dependent on a variation of the threshold voltage.
