  • Buffer circuit
    Patent number: 11271553
    Abstract: A buffer circuit configured to receive first and second input signals through first and second input transistors coupled to a first power voltage node, output a first output signal through a first output node and a second output signal through a second output node based on the first and second input signals. A load circuit is coupled among the first output node, the second output node, and a second power voltage node and a resistance value is adjusted based on at least one of the first and second output signals.
    Type: Grant
