Abstract
A voltage adjusting circuit includes a variable current generating means for generating a variable current to be supplied to a power source line, a decision voltage generating means for generating a decision voltage by using a power source voltage of the power source line, and power source noise detecting means for detecting power source noise of the power source line by using the power source voltage of the power source line and the decision voltage.
Claims11
A voltage adjusting circuit, comprising:
- a voltage generating circuit that generates a power source voltage of a power source line;
- a variable current generating unit that generates a monotonously increasing variable current to be supplied to the power source line;
- a decision voltage generating unit that generates a decision voltage by using the power source voltage of the power source line;
- a power source noise detecting unit that detects power source noise of the power source line based on the power source voltage of the power source line and the decision voltage;
- and
- a setting voltage decision circuit that decides a setting value for the power source voltage, based on a detection result by the power source noise detecting unit.
