Abstract
Aspects of the invention provide for equalizing rise and fall slew rates at an output for a buffer. In one embodiment, a method includes: measuring, simultaneously, rise and fall slew rates at an input of the buffer and rise and fall slew rates at the output of the buffer; generating a slew reference based on at least one of the rise slew rate or the fall slew rate at the input of the buffer; comparing the rise slew rate and the fall slew rate at the output of the buffer to the slew reference; and generating at least one of a rise control signal or a fall control signal for adjusting at least one of the rise slew rate or the fall slew rate at the output of the buffer.
