Abstract: A semiconductor device that can rapidly stabilize a control voltage for controlling an electric current source is provided. A semiconductor device includes a filter circuit that is provided between a control voltage generation circuit and an electric current source and removes noise of the control voltage. The filter circuit includes a first resistive element that is provided between the control voltage generation circuit and an output node that outputs the control voltage, a first capacitive element that is provided between the output node and a first voltage, a second capacitive element that is coupled between the output node and the first voltage via a first switch element. The second capacitive element is coupled between the first voltage and a second voltage when the first switch element is non-conductive. The second capacitive element is coupled with the first capacitive element through the output node when the first switch element is conductive.
