Abstract
Capacitive coupling may enable more tightly synchronized operation of components in a multi-domain distributed driver that provides slope-controlled switching of differential signal lines. One illustrative distributed driver includes: a first set of transistors each coupled to drive a first bus line; a first set of delay elements configured to enable and disable the first set of transistors sequentially; a second set of transistors each coupled to drive a second bus line; a second set of delay elements configured to enable and disable the second set of transistors sequentially; and at least one capacitance coupling a first node in the first set of delay elements to a corresponding second node in the second set of delay elements to synchronize signal transitions at the first and second nodes.
