Abstract
A power circuit is suitable for inclusion into a semiconductor apparatus, for example, and follows up the noise caused by the operation of an internal load circuit. When the voltage V.sub.DD applied to the internal circuit changes a relatively moderate amount due to such causes as the variation of an externally supplied power supply voltage V.sub.CC or the operation of the internal circuit, a negative feedback is applied to a variable resistance element by a voltage comparator and a variable resistance element driver. In response to an instantaneous variation of the internal circuit applied voltage V.sub.DD, the variation being caused by the operation of the internal circuit 100, for example, a rapid negative feedback is applied to the variable resistance element by a capacitor.
