OUTPUT DRIVER AND OUTPUT BUFFER CIRCUIT INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17889543 titled 'OUTPUT DRIVER AND OUTPUT BUFFER CIRCUIT INCLUDING THE SAME

Simplified Explanation

The abstract describes an output driver for electronic devices. The output driver consists of a pull-up driver, a pull-down driver, and a reference voltage compensation circuit.

  • The pull-up driver connects the output power supply voltage to the output node and raises the voltage at the output node based on a pull-up driving signal and a pull-up reference voltage.
  • The pull-down driver connects the output node to the ground voltage and lowers the voltage at the output node based on a pull-down driving signal and a pull-down reference voltage.
  • The reference voltage compensation circuit performs a short operation during transitions of the pull-up and pull-down driving signals.
  • The short operation involves connecting the pull-up reference voltage to the ground voltage or the pull-down reference voltage to the output power supply voltage.

Potential applications of this technology:

  • Integrated circuits and semiconductor devices
  • Electronic devices with output drivers, such as smartphones, tablets, and computers

Problems solved by this technology:

  • Ensures accurate voltage levels at the output node during transitions
  • Compensates for any variations in the reference voltages
  • Improves the overall performance and reliability of the output driver

Benefits of this technology:

  • Provides stable and reliable voltage levels at the output node
  • Reduces signal distortion and noise during transitions
  • Enhances the functionality and efficiency of electronic devices


Original Abstract Submitted

An output driver is provided. The output driver includes: a pull-up driver connected between an output power supply voltage and an output node, and configured to pull up a voltage at the output node based on a pull-up driving signal and a pull-up reference voltage; a pull-down driver connected between the output node and a ground voltage, and configured to pull down the voltage at the output node based on a pull-down driving signal and a pull-down reference voltage; and a reference voltage compensation circuit configured to perform a short operation during transitions of the pull-up driving signal and the pull-down driving signal, wherein the short operation includes electrically connecting any one or any combination of the pull-up reference voltage to the ground voltage, and the pull-down reference voltage to the output power supply voltage.
