Patent ID: 8638149

Claim:
A method for equalizing rise and fall slew rates at an output of a buffer, the method comprising: 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, wherein the input of the buffer is a signal input and the output of the buffer is an output for the signal; 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, to cause the rise slew rate to equal the fall slew rate at the output of the buffer.
