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.
