Abstract
In integrated circuits with internally generated supply voltages, during the run-up of the internal voltage generators, unintentionally high currents can arise through switching stages connected to the internal supply voltage. A control circuit provides for the initialization of the switching stages during power-up. The control circuit contains an inverter that, in signal terms, can be driven by a precharge signal and, on the supply voltage side, is connected to the internal supply voltage via respective transistors. During power-up, the transistors are switched off and then switched on. The precharge signal is forwarded to the switching stage via a further inverter.
