Abstract:
A driver circuit for driving an output signal in response to an input signal comprising:a. a pull-up circuit including a first transistor and configured to receive the input signal having an input voltage level;b. a pull-down circuit including a second transistor of the same type as the first transistor;c. an output node having an output voltage level and coupled to both the pull-up and pull-down circuits for providing the output signal in response to the input signal;d. a control node having a control voltage level and coupled to both the pull-up and pull-down circuits for controlling the pull-down circuit according to a state of the pull-up circuit; ande. a voltage reducing circuit including a first resistor coupled to the pull-down circuit and a second resistor coupled between the pull-down circuit and the control node for reducing the control voltage level and providing a reduced control voltage to the pull down circuit.
