Abstract
An output driver circuit includes a driving control signal generation block configured to compare a power supply voltage and a reference voltage and generate first and second driving control signals and first and second inverted driving control signals; a preliminary driving block configured to drive a pull-up driving signal and a pull-down driving signal with driving strengths set according to the first and second driving control signals and the first and second inverted driving control signals; and a driving block configured to drive output data in response to the pull-up driving signal and the pull-down driving signal.
Claims35
An output driver circuit comprising:
- a driving control signal generation block configured to compare a power supply voltage and a reference voltage and generate first and second driving control signals and first and second inverted driving control signals;
- a preliminary driving block configured to drive a pull-up driving signal and a pull-down driving signal with driving strengths set according to the first and second driving control signals and the first and second inverted driving control signals;
- and
- a driving block configured to drive output data in response to the pull-up driving signal and the pull-down driving signal,
- wherein the driving control signal generation block compares first and second divided voltages generated by dividing the power supply voltage with the reference voltage, and generates the first and second driving control signals and the first and second inverted driving control signals.
An output driver circuit comprising:
- a pull-up driving signal generation unit configured to receive data and generate a pull-up driving signal which is driven with a pull-down driving strength set according to first and second driving control signals;
- a pull-down driving signal generation unit configured to receive the data and generate a pull-down driving signal which is driven with a pull-up driving strength set according to first and second inverted driving control signals;
- and
- a driving block configured to drive output data in response to the pull-up driving signal and the pull-down driving signal.
