ABSTRACT:
The present invention relates to a circuit arrangement integrated in a semiconductor circuit. In modern microprocessor systems with high clock rates (50 MHz and more) special chips with narrow tolerance ranges as regards their switching speed are required. The circuit arrangement according to the invention compensates the switching speed fluctuations due to temperature fluctuations and process spread by generating an internal operating voltage and controlling said voltage in such a manner that it counteracts the fluctuations of the switching speed due to temperature changes and process spread and compensates said fluctuations.
