  • Patent number: 6100744
    Abstract: Integrated buffer circuits include an output driver powered at a first power supply voltage (EVC) and a voltage boosting circuit which drives an input (DOK) of the output driver and is powered at a second power supply voltage (VINTQ) having a magnitude less than a magnitude of the first power supply voltage. An internal power supply voltage generator is provided which generates the second power supply voltage at a level which varies inversely with increases in the first power supply voltage in order to minimize timing skew associated with the output driver. This is achieved by lowering the voltage of the signal applied to the input (DOK) of the output driver to compensate for the output driver being powered at an increased first power supply voltage.
