Abstract
An apparatus includes a first circuit and a second circuit. The first circuit may be configured to (i) generate a plurality of delayed signals each as a copy of an input signal shifted in time by a sequence of respective delays based on a control signal and (ii) change a number of driver signals that are active during each delay in the sequence of respective delays based on the input signal and the plurality of delayed signals to control a slew rate of an output signal. The second circuit may be configured to drive the output signal in response to the driver signals.
