US Patent 11854660 Slew signal shaper circuit using two signal paths

To mitigate pulse shape degradation along a signal route, the signal is driven from two ends. One end of the route is loaded and the other is relatively unloaded. The loaded route and unloaded route may traverse two different metal layers on a printed circuit board. The two routes may thus be related such that the unloaded route has less RC distortion effects on the signal than does the loaded route.
