  • Patent number: 11916548
    Abstract: A buffer circuit includes an input terminal configured to receive an input signal, an output terminal, an inverter, and a resistor-capacitor (RC) circuit coupled in series with the inverter between the input terminal and the output terminal. The RC circuit includes an NMOS transistor coupled between an RC circuit output terminal and a reference node, a resistor coupled between the RC circuit output terminal and a power supply node, and a capacitor coupled between the RC circuit output terminal and one of the power supply node or the reference node, and the inverter and the RC circuit are configured to generate an output signal at the output terminal based on the input signal.

  • Patent number: 10979049
    Abstract: A buffer circuit includes an input terminal, an output terminal, a buffer, and an RC circuit coupled in series with the buffer between the input terminal and the output terminal. The RC circuit is configured to increase a transition time between logical voltage levels of an output signal generated at the output terminal relative to a transition time between logical voltage levels of an input signal received at the input terminal, and the transition time of the output signal is based on a duration of a logic inversion of the input signal.
