  • METHOD AND CIRCUIT FOR GENERATING CONSTANT SLEW RATE OUTPUT SIGNAL
    Publication number: 20040165449
    Abstract: An improved output buffer having a substantially constant slew rate comprises a slew rate control circuit and an output driver circuit. The slew rate control circuit is configured at the input terminals of the output driver circuit to suitably control the slew rate of the input signal for the output driver circuit based on the level of voltage of a power supply for the output driver circuit. For increases in the voltage of the power supply, the slew rate of the input signal of the output driver circuit is decreased, while for decreases in the voltage of the power supply, the slew rate of the input signal of the output driver circuit is increased, such that the variation of the slew rate of the output signal of the output buffer is significantly reduced.
