<p>A power circuit to be preferably incorporated in a semiconductor device and for following noises due to the operation of an internal circuit serving as a load, which applies negative feedback to a variable resistance element (500) by a voltage comparator (300) and variable resistor driver (400) when the voltage Vdd applied to an internal circuit (100) due to the fluctuation of the supply voltage Vcc or operation of the internal circuit (100) fluctuates comparatively slowly. The circuit also quickly applies negative feedback to the variable resistance element (500) by a condenser (C1) for instantaneous fluctuation (noise) of the internal circuit applied voltage Vdd due to the operation of the internal circuit (100).</p> |
