Abstract
A method and apparatus for matching rise time and fall time in two differential signals. The apparatus includes a system that includes an scaled summer, a reference voltage generator, a comparator, and a storage device. The scaled summer receives two input signals and generates an instantaneous scaled sum of the two input signals. The reference voltage generator generating a reference voltage. The comparator compares the scaled summer output signal and the reference voltage and generates a comparison signal. The storage device stores the comparison signal. The stored comparison signal is usable to adjust one of the rise time and the fall time of both of the two input signals to match one of the fall time and the rise time of the two input signals.
