Logic buffer circuit and method

A buffer circuit includes an input terminal configured to receive an input signal, 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 includes a first transistor and an RC network including a resistor and a capacitor, the first transistor is coupled in series with the resistor between a power supply node and a reference node, and the buffer and the RC circuit are configured to generate an output signal based on the input signal.

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.
