Abstract
A circuit includes a driver circuit configured to generate a driving signal having a first edge, an output circuit coupled to the driver circuit via a connection to receive the driving signal on the connection, and a compensation circuit coupled to the connection. The output circuit is configured to generate an output signal in response to the driving signal. A second edge of the output signal has a slew rate corresponding to a changing rate of a voltage of the driving signal on the first edge. The compensation circuit is configured to be enabled at a beginning of the first edge to pull the voltage of the driving signal on the first edge toward a threshold voltage. The compensation circuit is further configured to be disabled in response to and after the voltage of the driving signal on the first edge reaching the threshold voltage.
