| description | PROBLEM TO BE SOLVED: To complete off-set trimming for a plurality of voltage regulator circuits in a short time.SOLUTION: A semiconductor device comprises: a plurality of differential amplifiers DEF each of which creates an output signal AOUT by comparing corresponding correction reference potential VRTRM with internal potential VINT appearing at power supply wiring 14; a plurality of output drives DRV each of which drives the power supply wiring 14 based on the corresponding output signal AOUT; and a voltage monitor circuit 60 which monitors in a state where any one of the plurality of output drivers DRV is activated and all the rest are inactivated, a plurality of output signals AOUT input to the inactivated plurality of output drivers DRV. According to the present embodiment, off-set trimming can be simultaneously performed for a plurality of voltage regulator circuits. Accordingly, regardless of the number of voltage regulator circuits, off-set trimming can be completed in a short time.
【課題】複数の電圧レギュレータ回路に対するオフセットトリミングを短時間で完了する。【解決手段】それぞれ対応する校正基準電位ＶＲＴＲＭと電源配線１４に現れる内部電位ＶＩＮＴを比較することによって、それぞれ出力信号ＡＯＵＴを生成する複数の差動アンプＤＥＦと、それぞれ対応する出力信号ＡＯＵＴに基づいて電源配線１４を駆動する複数の出力ドライバＤＲＶと、複数の出力ドライバＤＲＶのいずれか一つを活性化させ、残りを全て非活性化させた状態で、非活性化させた複数の出力ドライバＤＲＶに入力される複数の出力信号ＡＯＵＴをモニタする電圧モニタ回路６０とを備える。本発明によれば、複数の電圧レギュレータ回路に対して同時にオフセットトリミングを実行することが可能となる。これにより、電圧レギュレータ回路の数にかかわらず短時間でオフセットトリミングを完了することが可能となる。【選択図】図５ |
