  • Output buffer circuit with enhanced slew rate
    Patent number: 8289302
    Abstract: An output buffer circuit with enhanced slew rate is disclosed. A first and a second slew-rate enhancing transistor are configured to enhance the slew rate of the source transistor and the sink transistor of an output stage. A first control circuit and a second control circuit turn off the first and the second slew-rate enhancing transistors during the static state, and turn on the first and the second slew-rate enhancing transistors during the transition.
    Type: Grant
